Well, definitely not Atlanta, Georgia. A car is an absolutely necessity here, even if you DO live downtown - downtown's so scattered up and down Peachtree street, and the public transportation system isn't all that great. Plus nobody except young liberal 20-somethings and folks with too much money to care live downtown. Too many problems - crime, corruption, taxes. My parents moved OUT of the city of Atlanta when they retired because property taxes were killing them. Didn't get many services for their bux either.
Peachtree City is fairly self-contained, and it doesn't have all the problems associated with living in a big city.
