Football in the Southwest

I’m going to be living in Phoenix, AZ in September. I love college football. I know that I can go to Tempe to see ASU. Has anyone been to other cities during college football? I am thinking of Tucson, Flagstaff, Albuquerque, El Paso, Las Cruces, UNLV in Las Vegas, perhaps San Diego State? Any opinions on the stadiums? Opinions on the experience? Go ahead and tell me about other places that are close. Also, if you know of a good high school match up, tell me about it as well.
