We have been on many tours in Gettysburg, New Orleans, and such but it is usually about 30 people with a guide. Now, due to the pandemic, they are limiting the tour to 6 people and we were the only group that night. As a result, our guide, Christine, basically gave us a private tour that lasted over two hours. She was outstanding and it was a joy to be able to walk around the city and see the sights. We didn't see any ghosts but that was fine; we had a great time seeing Pittsburgh with our "own" guide. Excellent job.
