This was a worthwhile activity. Phil is very knowledgeable. He began with a brief city tour and then took us to the countryside to an Amish creamery and farm.
I would only add the following: to do a full Lancaster experience, take a guided tour of the city from City Hall or do the self guided tour. There is a lot of history embedded in this city.
Secondly, visit the Amish Village; although touristy, you will get a sense of how they live ,which is a very good backdrop for this tour.
Thirdly, if you have time, drive into the countryside for a few hours to experience the beautiful scenery-I recommend route 741 east of Strasburg. There isn't enough time on this tour to fully appreciate the scenery.
