While there are a lot of fun things to do when you're naked, I don't count bowling as one of them.
There are a few rules that everyone must follow. Nudity is required but women can wear bottoms. Sexual activity will not be permitted. Every participant must be 18 or older and must have a ticket, which you can see about by clicking here.
I've been getting back into bowling lately and there's not a chance I would do it naked! I bend over way too much, there's a lot of bad angles and frankly, nobody needs to see me in just my bowling shoes. And I wouldn't subject anyone to that. But if people want to go and be free then God bless them. Have at it!
There could possibly be some ball jokes thrown around too. I'm just guessing.
