One of the clubs out there was hosting some mud wrestling shows one nite a week, I believe. This was a couple of years back so not sure if still doing them or not. I cant even remember the name of the club anymore...but I do know that Tweety used to go over and wrestle there on occasion. So you may want to ask around when you get to Vegas.
Also, you may want to look up a gal named Rosy Rocket. She is from Thailand, very attractive and is a pretty fair wrestler.
