Best Arizona Places to Retire To

Arizona has some very good small towns to retire to.  If you know of any AZ town you like, please post a description here so we will all know about it. The more descriptive the better but even just a name will help and we can look in to more details.  Why do you like it   I have heard that some ghost towns around Arizona are being settled again by retirees. Anyone know of any of the towns that this is happening?

Of course Phoenix area with the Sun City and other active adult communities is a great retirement draw. Tucson also has a number of active adult communities. Arizona certain appeal to retirees.
