The Yuma Patriots were started after the founders son was beaten, robbed, and had his truck stolen by illegals in the Imperial Sand Dunes Recreation Area. He got fed up, and decided to do something about it. He also went to Mexico and recovered his son's truck on his own.
I read the story about the son being beaten and his truck stolen but never heard anything about the father going to Mexico to retrieve the truck. That must be a story in itself. If you know the story, please post it. I'll bet it is a good read.
