Besides U of A, I haven't heard many positive things about Tucson as a hip place. It's pretty much just the University, retirees, a new working class, and immigrants. I live in the Phoenix area, and for the 5th largest metro area, it's a breeze to get around. I've always thought Prescott, AZ had a fun vibe, as it's got some snow, some warmth, and no humidity. It has been rated the top location to retire to several times in the last 10 years
