You might take a look at Peachtree City, Georgia. About 35,000 people, 35 miles southwest of Atlanta. It's a golf cart path community, but the path system isn't limited to neighborhoods - goes everywhere in town, and just about everyone has a cart. The town is built around three golf courses, and the schools are good. The result is a sizeable retirement community mixed with a lot of families. There's good shooting 30 minutes or so away in Griffin (Cherokee Rose) and Gay (Big Red Oak Plantation), and you're close enough to Atlanta to get there when you want. Worth a look.
