I live in the Phoenix area, and agree. It's a very spread out, sprawling metropolitan area, with no real public transportation system to speak of. There is a light rail in the center of town, but it's limited in where it will take you. And there are city buses, but they aren't that effective either. I think I mentioned this to Rabshakeh prior to his visit here.
I live on the north side of Scottsdale, and to go to downtown Phoenix for anything is a minimum 45 minute drive if there's no traffic. Or further if you're going to Mesa or Chandler or other areas.
It's got its charms, but it's not a (relatively) compact city with a center where many people live, work and play. Unlike Philadelphia, where I moved from, which has a very effective subway and bus system. Just don't pay attention to panhandlers - as in most larger cities.
