What's in Arizona?

I just found out that I’m going to be stationed at Davis-Monthan AFB in Tucson Arizona. I’ve never been to that state and I’m excited. Is anyone reading this from Arizona? All I know is that there is the Grand Canyon, and I don’t know how far that it is from Tucson. I also hear that Phoenix is a pretty nice city which is not too far from Tucson I don’t think.
