At the moment I'm reading a book about a guy that traveled around the world for several years. He is writing about his travel experience and one thing that he mentions in almost every country is that he meets groups of Israeli travelers that take pictures of themselves in front of famous landmarks. However, they're always naked. He mentions that this weird behavior is known among the experienced travelers.
So my question is: Is it really true that Israeli traveler groups have a favor for shooting pictures naked?
