No. It sucks, doesn't it! No. There's no public transportation to the Rev's games. There used to be, back in like 96 or 97, there was a bus, and maybe the train for a short period of time. You can take a commuter rail train to a nearby station and then take a taxi. Check www.mbta.com (I forget which two are closest). However, the commuter rail doesn't run much on weekends, and I doubt much is running at 10 p.m. on a Saturday night. Maybe someone here will give you a ride, especially if you offer to pay the $15 in parking! My car's full, sorry!
Actually... I think the closest train stations to the stadium are Walpole or Norfolk - still too far to walk though.
