Paris is a romantic city. The architecture, the lights, the food, the language; it's hard to deny that this city is a place for love.

One of the classic expressions of romance in the City of Light is the collection of love padlocks on some of Paris' most classic bridges. Love locks are a simple thing: a couple writes their names on a padlock, locks it to one of the bridges, and if they are really committing to everlasting love, throws the key into the Seine.

The weight of love in Paris is so big that a few years ago, town hall was concerned about the influence of the locks on the city's architectural integrity, and one night, all of the thousands of locks were cut down - although the culprit remains unknown. But even French bureaucracy can't win in the battle of love, and locks returned, in all colors and sizes.

You'll find the biggest assortment on Pont des Arts and Pont de l'Archevêché (which bridge you choose depends on which type of love you are trying to express), where Flickr user jrodmanjir snapped this photo.

It's my turn on the helm of Instagram this week, which is great news because I'm traveling through a southern swath of Spain. Expect plenty of photos from Seville and Granada as I wander between cities, awkwardly bumping between glasses of Rioja and dishes of paella.

In case you missed it, we're in the opening weeks of our Instagram feed launch, and we're leaning on some of our well-traveled bloggers to populate the feed. Stay tuned for dispatches from Maui, Paris, Cabo and even Afghanistan over the coming weeks, and travel vicariously through our team.

Meanwhile, check out our Instagram page over on instagram.com/gadlingtravel.

When getting ready for take-off of any flight, we can take our seat promptly upon boarding the plane, stow our gear, be courteous to our fellow travelers and use electronic devices until instructed to power them down. Those activities are all just fine. On the other hand, smoking in the lavatory, joking about bombs or otherwise disrupting operation of the aircraft are serious matters that can get us kicked off the plane. But what other actions taken on board a commercial airliner can get us in trouble?

Checking in with Law.com's legal blog watch, the list is long.

• Stripping naked or saying the F-word can get you escorted off the plane.
• Get into a fist fight with the passenger in front of you who reclines their seat in the air and the pilot may turn the plane around and return to the airport, escorted by a pair of F-16 fighter jets
• Pretending to be a soldier to get a complimentary upgrade to first class can not only get you kicked off the plane, but result in being arrested. The charge: second-degree impersonation.
• Inhaling from an electronic cigarette or throwing bags of snacks at flight attendants can result in a charge of "interference with the flight crew," a federal offense that will cause the FBI to greet you when the plane lands.
• Take a photo of the name tag of a less-than-helpful flight crew member can get you on the No-Fly list, if not arrested.
• Dress code violations like wearing short denim shorts that make it unclear whether ladies are wearing panties, especially when those shorts are worn with a baggy T-shirt can get you kicked off the plane.

Coffee addicts bound for Scandinavia might want to consider a dip in an icy fjord as an alternative morning pick-me-up. The Wall Street Journal has calculated that a grande latte in Oslo will run Americans a jolting $9.83.

Helsinki and Stockholm are also cities offering the top five most expensive Starbucks lattes once the dollar is converted into the local currency.

The paper did the math on 25 major cities around the world (including Beijing at $4.81) to illustrate an economic principle called "purchasing-power parity," or "a crude way to compare the relative strength of currencies." Of course, avid travelers don't need this Starbucks-green bar graph to know that the peso is a lot friendlier to gringo wallets than the euro is, but that conventional wisdom doesn't always translate in the language of Starbucks economics. Otherwise, how would one explain that a grande latte in London is cheaper than one in Atlanta, despite the dollar's weakness in the U.K.?

According to the WSJ, most foreign Starbucks are significantly pricier than the U.S. outlets it also includes, but hey, maybe that's what average Joes deserve for patronizing an American company overseas instead of opting for a local purveyor.

How much is too much to nurse your Starbucks addiction abroad?

You'd think archaeologists would have found all the pyramids of Africa by now, but two recent discoveries show there's a lot more discovering to be done.

A team of archaeologists working in Luxor, Egypt, have just announced they've discovered the pyramid of Khay, a powerful vizier of the Pharaoh Ramses II (ruled 1279-1212 B.C.). The pyramid was made of mudbrick and originally stood 49 feet high.

In the seventh and eighth century A.D. it was dismantled and turned into a Coptic Christian hermitage. Hieroglyphic writing on the surviving bricks told the archaeologists to whom the pyramid belonged.

Earlier this month, archaeologists announced they had found the bases of at least 35 broken pyramids at the site of Sedeinga in Sudan. They're about 2,000 years old and belong to the kingdom of Kush, which lasted from c.1000 B.C. to 350 A.D. before finally being conquered by the Empire of Axum in Ethiopia. For almost a hundred years from 747-656 B.C., the Kushites ruled Egypt as the 25th dynasty.

The Sedeinga pyramids really just pyramid-shaped tombs. The largest measures 22 feet to a side, while the smallest is only 30 inches to a side. Others in Sudan, such as those at Meroë, are much more grandiose. Those at the pyramid field at Nuri, shown here courtesy Vít Hassan, are up to 150 feet tall.

Last year, a satellite survey conducted by Dr. Sarah Parcak of the University of Alabama found 17 suspected pyramids.

So how could these pyramids go missing? Well, most pyramids were much smaller than the famous ones at Giza and Saqqara that we always see pictures of. Shifting sands and erosion helped hide them. In the case of the Sedeinga tombs, later people took stones from them to build other structures.

Even some sizable pyramids have all but disappeared because they were made of inferior materials. Some of the last pyramids of Egypt are barely visible today because of shoddy workmanship or having been made with mudbrick instead of stone.

Size matters – with tunnels, anyway. Most lists of the world's most spectacular designs pant over the longest passageways, like Norway's Laedral Tunnel, currently the record-holder at 15.25 miles.

But beauty before distance, I say. Give me the arched canopy of tart pink cherry trees in Bonn, Germany, over a cold engineering marvel anytime. Or Shanghai's psychedelic light show inside the Bund Sightseeing Tunnel (pictured above). Or a simple rock cutaway in South Dakota with a million-dollar view. To that end – short trip though it may be – here's a photo tour of the most striking destination tunnels.

There's something poetic about the very existence of tree tunnels, formed by nature instead of built to conquer it.

Rua Gonçalo de Carvalho in Porto Alegre, Brazil
This high-reaching green carpet in the middle of the city, formed by more than 100 tipuana trees pressing up against tall buildings for several blocks, was at risk of being uprooted to make way for more development before residents won a fight to preserve it. Now the tree tunnel is a protected heritage and environmental site.

The National Park Service has announced that the official length of Mammoth Cave now surpasses 400 miles as ten miles of newly mapped chambers and passageways were recently added to the cave complex. Park officials say that these additional miles were the result of a series of smaller, more incremental finds, and were not the result of a single major discovery. Exploration and mapping of these new areas were conducted in partnership with the Cave Research Foundation.

Carved out of the central Kentucky limestone, Mammoth Cave was already the longest cave system in the world prior to the addition of these new discoveries. In fact, it is so large that it is more than twice the size of the next longest cave. Mammoth's massive underground complex attracts thousands of visitors on a yearly basis ranging from curious travelers to full-fledged explorers and spelunkers. Some of its more famous locations even have names, such as the massive Grand Avenue and the aptly named Fat Man's Misery.

The Park Service conducts daily tours of Mammoth lasting anywhere from one to six hours in length. Some of those tours are along relatively easy-guided paths while others venture far into the darkness to decidedly more challenging and cramped places. The popular Grand Avenue tour for instance is a 4-mile, four-hour trek that is physically demanding, while the hike to the beautiful Frozen Niagara is a much easier quarter-mile walk that is safe enough for both children and older visitors. Both provide fantastic views of the interior of the cave that simply must be seen to be believed.

If you're looking for a destination for an upcoming trip to a national park this summer, Mammoth Cave National Park is one of those places that will delight and amaze the entire family.

I've been dimly aware that it's possible to get one's shoes shined at airports the world over for many years. That said, I'm a chick, and despite my boot obsession, I usually travel in Chuck Taylors. I don't know from shoeshine, other than my love of Johnny Cash ("Get Rhythm," anyone?).

A couple of months ago, however, I found myself with time to kill at Denver International Airport (DIA), en route to work a trade show. A deep, syrupy voice called out, "Shine your boots, ma'am?" I looked down. I was wearing my favorites, a pair of motorcycle boots I'd scored on Ebay. They looked like hell after tromping around in the mud and snow.

"How much?" I asked the kindly-looking black gentleman wielding a clean rag. "Whatever you feel like contributing," he answered.

Seconds later, I was perched atop the adult version of a booster chair, observing the frenetic energy of the airport. I learned the gentleman in question's name was Leonard, and he'd lived in Denver for over 30 years. As we talked about how the city had changed, and waxed poetic about why we'd both chosen to relocate to Colorado, he brushed, polished, massaged and buffed my boots until they glowed. He sealed the seams along the soles, and meticulously attended to the areas beneath the buckles and straps.

Ten minutes later, I was boarding my flight with glossy, weatherproofed boots (my version of business casual), and a vivid mental picture of early '70s Denver. Leonard had some cash in his pocket, and I like to think that he, too, came away from the encounter richer not just financially, but emotionally.

Having a genuine, non-self-absorbed conversation with another human being at an airport is all too uncommon these days. Let's face it: most of our exchanges consist of requesting a specific size of latte, or bitching about our lack of upgrade.

Now, whenever I'm at DIA, I get my motorcycle boots shined, both to extend their life, as well as for the connection, however fleeting, to another human being. And yes, I like that I'm supporting hard-working people earning an honest living. I haven't seen Leonard again, but I never fail to have an interesting conversation, and learn a little something (many of the people working for this particular company, Executive Shine, are immigrants). If only I could travel in my high-heeled boots more often.

Today is International Pretty Brown Girl Day, a movement launched a few years ago that seeks to "address the harmful messages about skin tone and beauty in media" and is "for little girls of all ethnicities to send the message that brown skin is indeed beautiful."

Knowing a couple of pretty brown girls who are facing racism here in Spain, I understand the reasoning behind this, but I don't think it goes far enough. Instead of merely aspiring to be pretty, girls are better off aspiring to kick ass, so by the power invested in me by myself, I hereby declare today to be International Kickass Brown Girl Day.

This is inspired by a little Nepali girl I met many years ago. I had just come back to Pokhara from trekking the Annapurna Circuit and Base Camp and needed to return some gear to a rental shop. As I entered I saw the proprietor was gone and had left his daughter, who could have been no more than 10, in charge.

Two burly young Israeli guys were there arguing with her. They were returning some gear and didn't want to pay for that day, even though it was early evening. The girl insisted that they pay an extra 100 rupees (a little more than a dollar) because the shop was about to close and there was no way she'd rent that gear that day.

The Israelis didn't see it that way.

"No, we don't have to pay!" they shouted, towering over her and acting aggressive. They actually puffed out their chests and clenched their fists... at a little girl.

Shit, I thought. I'm going to have to jump in and protect this kid and there's no way I can take both these guys. Hopefully the neighbors will come in time to help.

Turns out she didn't need me. She furrowed her little brow, stuck out her slim little hand with the palm up and said in the most forceful voice imaginable, "NO! You pay me 100 rupee!"

They backed down.

It's one of the most impressive things I've seen in 25 years and 36 countries of travel.

Little brown girls have it tough. Disproportionately poor and discriminated against, many still play sports, go to school in underdeveloped areas, and kick ass in various other ways. So check out the gallery for some inspiring images, and be sure to celebrate International Kickass Brown Girl Day ...

... because girls who kick ass are automatically pretty.


This photo shows girls in a rural school in Ethiopia. Most don't have electricity or running water at home and have to walk several miles to get an education. Photo courtesy Almudena Alonso-Herrero, a kickass pretty brown woman who used to be a kickass pretty brown girl.
