We had an absolutely great day out a few years back at the Arizona State Fair  in Phoenix - If you're visiting mid-October time it makes for a great day out with a Midway fun-fair, exhibitions, vendors, shows & an awesome Pro Rodeo programme - Best of all end the day with one of the many top billing country stars appearing most nights over the two week or more schedule


I've not made it yet myself but I've also heard great things about the  Tucson Rodeo  at the Tucson Rodeo Grounds late-February time
