I'll give you an assignment. Run next door to SC and find somebody who can tell you (and later me) how pea-shellers work. Nobody could or at least nobody would, tell me.
@Jammy At least you have pretty country to travel through. If there's ever an ice storm down there, STAY OFF THE STREETS, but get a front row seat, preferably with a telephone pole in clear view. That's what they're going to hit just after they hit the brakes.
