Straight Cash Homie

I have never been to vegas myself but several of my friends have. I can't imagine that there is a lot around the area over there. How exactly did they manage to create a giant city in the middle of a desert anyway. So I probably won't be on the lookout for Las Vegas travel deals but obviously plenty of people go so there must be a lot to do, besides gambling of course. Talk about expensive vacations. I probably don't even want to know how much money people waste out there.
