Fremont experience is rather nice.  I believe they have tours of hoover dam, so a car wouldn't be required for that one.
Descartes has a good post, so follow his tips as well.  If you're into snowboarding, there's actually a small ski resort about an hour or so out.  Barely anyone is there.  I love going to that resort.  Arg, I forgot what it's called.
