I am a History Buff and I did a Walking Tour, Hop On Hop Off Tour, Duck Boat Tour and Ghost and Gravestone Tour. All of them provided their own unique perspectives of the history of Boston. The characters dress the part. Initially they can be spooky but as the tour progresses you can see what wonderful people they are.
I need to give a shout out to a young lady-Evil. The company had at least 5 tours scheduled from 530 to 800 PM. She had to wait in the cemetery in the dark for each tour to arrive. The tour is not so much about scaring you. It's more about giving you the Darkside of Boston's History as well as visiting the graves of our Revolutionary Heroes.
