Fifty years ago, when I did most of my vacation traveling, there is one thing that I did not see at popular tourist attractions. I have enjoyed viewing the most famous paintings and sculptures in the world's most famous museums such as the Louvre, the Tate Gallery, the Galleria degli Uffizi, the Doge's Palace, and dozens more, yet did not see this one thing. I have been to the Eiffel Tower in Paris, The Tower of London, the Pantheon and Colosseum in Rome, the Acropolis and the Parthenon in Athens, and other historic sites but did not see this one thing.

I have been to palaces in Germany, botanical gardens in the Netherlands, beer breweries in Czechoslovakia, ski resorts in Poland, Mozart concerts in Austria, Dracula's Castle in Romania, health spas in Hungary, beaches in Yugoslavia, and yet did not see this one thing.

Sometime in the past two decades I touched the white marble walls of the Taj Mahal, gambled in every major casino in Las Vegas, was an audience participant in the pilot episode of the King of Queens TV series, witnessed a rescue at sea, and yet never saw this one thing.

So what was this one thing? Naked Tourists. That's right - in all my travels I somehow missed seeing naked tourists which seems to be all the rage nowadays.

CNN, 20 Mar 2014, Peru to tourists: 'Stop getting naked at Machu Picchu!'

Watch out for bare butts when traveling in Machu Picchu -- incidents of "naked tourism" at the 15th-century Inca citadel are on the rise, and getting under the skin of Peru officials.

According to the Peruvian Times, four American tourists were detained on March 14 for getting naked and posing for photos at the site.

In a pair of separate incidents earlier in the week, two Canadians and two Australians were detained for stripping down for pictures at Machu Picchu.

The bare-it-all episodes followed a 2013 incident in which a naked couple was videotaped by other tourists while streaking across Machu Picchu's grass field and bounding down a stone staircase like a pair of adolescent antelopes.

And it's not just at famous historic sites, tourists are showing up naked everywhere:
