My sister & I are meeting up in Vegas. She's only been once for a convention off strip & I'm kind of nuts about Vegas. She can only stay for 2 1/2 days. I was thinking on our first full day we'd go see the Dam in the AM (rent a car). I went to the Dam pre 9/11 so the tour is from what I understand very different now... Is it worth a half a day to go see the dam? I'm thinking we will head downtown later that day - maybe do neon museum &/or mob museum and then take in Fremont. So dam - opinions ... Especially if you've been a wile ago and recently Thanks!
