Greetings From Madison Wi - My family will be Vegas for vacation Aug. 22-27. My wife and I have been to Vegas 15 times all without the kids. We figured it would be a good time to show them what it is all about. We have a 13 year old son so that will be somewhat of a challenge. I think I have enough things planned so that he won't get bored - Hoover Dam, Atomic Testing Museum, Red Rock etc. Any advice for things to do with a teenager would be helpful.
