A spot that has always been kind to me is where the Lower Mystic drains into the Mystic River. There's a rotary there and you can park on the side of the road. Fish on either side of the bridge and you can get smallmouth and more sunnies than you'd ever want!
question for bcdokind: where do you park when you fish the mystic river bridge in medford (which actual road). im familiar with the area you are talking about but it seems that everything is posted no parking. i havent checked for a place to park on the nearby side streets though. are you parking in a legal parking area or just kinda winging it?? thx for any help. take care all.
