I loved the Hoover Dam tour!
Only bad thing was that the elevators at the Dam went down and so we couldn't complete that part of the tour. I was actually right about to get on the elevator when they got to the limit...
Steve was an awesome driver. He had lots of interesting tidbits of info and I didn't hear him "slurp mucus". Seriously people, if you're looking for a great experience try them and ask for Steve. I dunno what hair other peeps got up their ass about him, but he was just awesome.
