Does anyone know of any interesting stops along I81 from Knoxville to Lancaster PA? I am looking for inexpensive bed and breakfasts or other interesting places to stay suitable for me and my 10 year old son I am also looking for any interesting stops along the way. I took my son to Lancaster PA for spring break two years ago, stayed at a farm, visited and had dinner with an Amish family and just drove around for a few days. We travel extensively thoughout the US and he thought this was the best trip ever and wanted to do it again. We didn't drive last time so I don't know how to break up a 14 hour trip on this route. Thanks!
