    "OFallon is a great city with a small town feel. i feel safe here, feel safe to go to any part of OFallon. You can live in a subdivision or you can find plenty of homes on 1 to 30 acres on these outskirts of town and only be 5 to 10 from large malls, mini malls and just about every well known stores or small local stores. During rush hour traffic can get a little backed up but it's only a 10 minute backup at most. "
