I've been before and got to spend a few days touring the town (Freedom Trail, Cheers, Fenway for a Sox game, Harbor, Union Oyster House, etc)….. trying to see what I've missed for my family. Got a killer deal on flights up there this weekend so we're going for a few days. Figure we'll do Plymouth Rock, Salem, Freedom Trail, Fenway Tour, Skybridge, Paul Revere House. What am I missing?
