If you get to Central PA there is an exit near PSU on 322 for Bellville [close to Lewistown]
On Wed everything around here centers on this place. It has a livestock auction which has turned into a major event. There is a huge flea market and yard sales galore. It is also the focus of most of our antique shops for this area. You can say it is a 12 mile flea market/yardsale.
Now the good part. Stop at Peachey's. It is a butchershop resturant. All the food is homemade by Amish/Mennonite cooks who work there. They have a breakfast buffet to die for. Actually without the shopping Peachey's alone is worth the trip. There are several other fairly good ones in the area as well as Amish stands set up all over the place. A couple of nice B&Bs with good food also if you want to spend the night.
