Lol, but yes. I know that "Great Walls" have become a bit of a thing, but I don't believe that people actually get dressed for them. Its more of a meme than anything else.
I mean, don't get me wrong, it's always awesome when you can get any kind of backdrop that adds to the visual appeal of a fit pic, but I think that that is about it. Its nice when you have it, and I am sure that when people happen upon excellent backdrops, they do intentionally take pictures there, but I don't think that they actually get dressed with that intent.
