Tim was a fantastic guide. Since it was 9/11 we got a bonus observing a solemn event at the Betsy Ross house with policemen, fire fighters, army and bag pipes. He is a knowledgeable historian and throws in the humor. I told him that I wish I would have had such a teacher when I was in high school. Even with it drizzling, the tour was well worth it. I went back on my own and revisited some of the sites.
