Where will you be coming from, LR?
I always have driven and if you are staying in DT LA or in Pasadena both of those areas are pretty quick and easy drives. I've seen groups of buses parked at the stadium but I don't know where they come from specificly.
Check the Dodgers web site for parking guidelines under: http://losangeles.dodgers.mlb.com/la...rk/parking.jsp
I didn't see any references to mass transit on the site but maybe I missed it.
