I just moved to Tucson about 2 weeks ago (wife is going to school here). It's a college town (U of A). Lots of good Mexican food!
As far as stuff to do, theres the normal stuff like movies, bars, bowling. I havn't done much here yet since I just moved. There seems to be a lot of used CD stores around if you are into them.
The view is nice here. Just about wherever you are in Tucson, you can see the mountains since it is so flat.
It is still pretty hot, but it is cooling down.
