If you are a visitor to this city and don't have plans to leave the greater phoenix area consider the bus and rail system. Ended up using the system to get around for a grand total of $3.50/day which gave me unlimited rides for the whole day. A word of warning i met quite a few scammers one gig is the obama supporters give a story about needing some money for a unused full day ticket DON'T do it the ticket looks real but is a fake and they do have farecheckers that check randomly.
