Anything worth seeing from Baltimore to Niagara Falls?

My girlfriend and i are driving up to Niagara falls the week of the 6th of April. Its a bit of a drive (8hrs) and i was wondering if there was anything cool to stop by in Pennsylvania. Maybe a bed and breakfast, Amish village, good bar, interesting restaurant. I'm really open to anything.Anything worth seeing from Baltimore to Niagara Falls?
Lancaster County would be a bit off-route.



To be honest, I can't think of any really interesting places from Baltimore to Niagara Falls that wouldn't take you off-route.



Do a 'search' on Harrisburg or Williamsport.



Maybe check out the Corning Glass Museum in Corning, New York ?Anything worth seeing from Baltimore to Niagara Falls?
Stop by Hershey, PA for a bit
