I'm looking for a small town in Alabama. A small rural town where everybody knows everybody
with a low crime rate. And that has small water sources, such as creeks, or rivers, or lakes nearby
where people go swimming. I have a son so of course I want good schools. And a nice downtown
where there's a bunch of little, locally owned shops and a bakery and stuff like that. I don't really want
a rich town, but not too poor. I want it to be a religious town with a nice little church too.
If anybody knows of a town like that I would appreciate the info!

Hamilton. Lots of water and convenient stores. Everyone knows each other (they're all related).
Schools probably aren't great. Lots of churches (not sure why you'll find a town in Alabama with only
one church).
Auburn is not a small town, but it has everything except for the water sources. Plus the schools are
great.

I live in Anniston, which is fairly small. The schools are terrible. Everyone goes to church and
knows everyone else, but as far as safety goes, the crime is worse than that in the city Detroit. Haha!
