Crazy Place to Make Sex

I often hear on TV or read in magazines the question : "Where is the craziest you've had sex ?", and a lot of people have various answers. Today I've found these pictures that made me laugh, and remember that in this world are a lot of crazy people with a lot of crazy ideas. I don't want to say that I don't like this idea, but is something really extreme and you need some guts to try something like this. And in the end ... "Where is the craziest place where you've had sex ?" and maybe you'll show us some pictures. :P
