Stay away from the West Side, unless you are broke and don't mind gun shots, crack dealers, illegals and being robbed. North side of town is good, east Phoenix is still ok, Scottsdale is good, Tempe and Mesaco are ok too. The best part of Arizona summer is that the girls start taking off their clothes!
I would never want to live in Phoenix. I don't like the heat, traffic, rude bus drivers down there and its easy for me to get lost cuz Phoenix is to big for me. But I love Flagstaff!!!
