Preston was a retired High School teacher, supposedly a great guy. Eustace puts on a really big act for the show though. Whether or not he gets those turnips sewed before the rain will not decide whether he eats or not. I remember one episode where he rode his horse into town at break-neck speed to make sure his property taxes got paid. They made it look like his property would be sold if he was one hour late. Turtle Island Reserve is just outside of Boone, NC, and is a busy tourist attraction.
Tom is retired now and lives in FL and Marty has retired from his real job as a Smoke Jumper.
