If the kids are older take in a Red Sox game at Fenway Park, although it will cost a pretty penny. Otherwise, settle for a very interesting behind the scenes tour of the place which includes a history of Boston’s oldest baseball team and such luminaries as Ted Williams. Obviously, these tours go on when the stadium is not in use although some warm-up pitchers might be on hand. Fenway Park is one of the last of the old-time baseball fields and has gained historic status so it will not be torn down.
