If there is a rule or subrule entitled “Board and Pieces”, add the following text to the end:

The Washington DC Metro map (http://washingtondcstay.com/sitebuildercontent/sitebuilderpictures/Metromap.gif) is gamestate and is considered part of the Board, except that no Station on the Washington DC Metro map is an eligible starting location for any Player’s Piece nor may a Player’s Piece be moved to a Station on the Washington DC Metro map by operation of a rule that permits an Off The Board Piece to be moved to a Station.  The Lines on the Washington DC Metro map may be referred to by the first letter of the color of that line, in lowercase (i.e., r for Red Line; o for Orange Line; b for Blue Line, g for Green Line and y for Yellow Line).
