Tim was our guide and, as I understand it, he also started the company a few years ago. Very historically informative as well as entertaining. It was s warm day and he did a nice job of keeping us in the shade as much as possible. He made an effort to pull a few of the kids in our group into the discussion. I learned a LOT on this tour - more than I expected. I was hoping to learn, more than just see, and he did not disappoint. I would highly recommend this walking tour to anyone that is looking to learn and enjoy the experience as well. RS - from MD
