vegas is pretty shitty unless you're a dedicated douchebag +1. but I places like vegas I wouldn't want to never see them, even once. there are maybe 50 cities I can think of that I have been to once and have no desire to get back to. there are only a handfull of cities in africa and maybe in siberia that I have no desire to see, even once. also chernobyl. aside from that, I'd pretty much like to see everyplace.
