Each October Salem Main Streets colaborates with the Naitonal Park Service, the City of Salem, the Chamber of Commerce and Destination Salem to produce an information booth in Town House Square. Town House Square is the intersection of the Essex Street Pedestrian Mall and Washington Street, just two blocks from the MBTA train station.
The info booth is staffed by volunteers on weekends in October, and they answer thousands of questions, which range from, "Where's the bathroom?" to "What should we do today?" to "What's good for kids?" They also answer the occasional, "Where do we park?!" screamed from a passing car.
If it's questions you have, it's answers they've got, as well as maps, brochures, and program listings.
Oh, and the closest (public, indoor) bathroom to the info booth is at the National Park Service Visitor Center at the corner of Essex and New Liberty Street.
