There are A LOT of tours in Salem, and I've taken quite a few. A lot of them tend to fall into two categories: witch trials, or paranormal. And if you take a bunch of tours, you'll find them overlapping quite a bit - to the point that, as you visit different locations, you'll have a pretty good idea of which story is about to be told.
THIS tour is a bit different. It focuses on a "then and now" approach, showing you images, via vintage postcards, of how Salem used to be, versus how it is now. The guide, Grace, will take you to locations that many of the other tours don't go. She'll provide stories that other tours skip, or only mention in passing, and she'll pepper in some stories from her personal experiences.
Plus, being newer, the tour size tends to be smaller and more intimate.
All in all, it was a nice change, and provided me something different from the other tours that all seem to draw from the same well.
