Recently I visited Salem, Massachusetts and, although my focus was not on witches, it is a most interesting city. I like to walk on holiday, or when in a new area, and the traffic, signage and one way streets were a challenge. The town of Salem has capitalized on this. As a pedestrian you are the Kings and Queens: the traffic halts.
When deciding what to do in an afternoon rain shower we discovered the Peabody Museum in Salem. We viewed the Turner Exhibit and the California Exhibit. It was exciting to see the many design items from California...look for the bathing suits and Airstream travel trailer.
