It is often the case that one of our club members can drive players without a car to Alewife or some other MBTA stop after the last bus from Lexington has left (at 10:05 p.m.). Seeking such a ride is best done early in the evening, since most players who stay late do not head in an appropriate direction.
The last inbound commuter rail train stops in Concord at 11:14 p.m.; catching a ride with someone going near there is a possibility, but such a ride may be too late for that train. That train makes these further stops:
A "flag stop" means that the train stops to discharge passengers on notice to the conductor and to pick up passengers on the platform visible to the engineer.
