Took the family to the "snack factory" tour at Herr's a couple weeks ago and it was really nice. It's FREE - so you can't beat that. The tour takes about an hour. It starts with a silly little movie and then you walk though the plant. You end eating hot chips. The kids and I both thought it was pretty cool. Only open M- Fri, not Fri afternoons, you must call ahead for reservations.
