A small town in South Carolina in the Columbia area. It's home to Peachtree Rock, a section of the woods known for several large rocks in that location that are shaped like upside-down pyramids. There is a Diamond dog food factory as well. As far as last names go, there are a lot of Pounds and Sightlers running around. The town is associated with Swansea, a neighboring country town. If your an adolescent living in Gaston, you'll go to Swansea's high school. Unfortunately, Gaston is saturated with drugs and there has been a lot of methamphetamine production going on in recent years, as well as a lot of busts. The town is starting to grow. A Food Lion, several pawn shops, liquor stores, a Wendy's and a Burger King have recently been built, among other things.
Person 1: Let's make a trip to Gaston to visit Peachtree Rock!
Person 2: Okay, sounds like a plan.
