I enjoyed the tour, the only thing that I think travelers need to know is that it takes 2 hours. Some of the detail was too much. I think the presenters should just hit the high points, we are never going to remember the amount of details that we were given. There was also a lot of standing around with no place to sit down and it was a hot day. Wear very comfortable shoes, the ground is rocky and uneven.
No masks were required, if they were we would not have come to Boston.
