Sandhills region of NC is about as far north as you’ll find widespread peach farming. If you vacation at NC or SC beaches, look for the roadside peach stands and buy a couple of bags full. That’s what we do. You can peel, slice and freeze what you can’t eat, they take it reasonably well.
Some of the best peaches I’ve ever eaten are from Chambersburg, PA. When I was a student at Gettysburg College, there was a roadside stand right along US30, and I’d buy them by the bushel.
