I used to go Rte 30 a few times a year, used to just love the old stone barns and flounder houses. My ex's uncle was from York, and had told of of so many great unknown places to stop on the way down to visit them in VA. The farmers markets are the best - dried apples, cold cuts and pies to die for!
I still make the ham/fried apples and dumplings dish they taught me, but can't for the life of me remember the name of it. Shnitz and kepp, or something? That Pennsylvania Dutch food sure sticks to your ribs.
