There's one, maybe more, in Deale at the Tri-State Marine gas dock/supply store (formerly JJ's Tackle) on Rockhold Creek. Head straight out of Herring Bay east over towards Poplar Is. When you get to 50 feet depth troll spoon umbrellas or hoses 120 back with 8oz and the blues should be snapping. Been working for me the last few weeks. Good luck! Andy
Backyard Boats in Shadyside has a decent ramp. Puts you on Parrish Creek at the mouth of the West river.
Personally i'd just go to Ches beach, much nicer ramps and only a few miles south of Deale - as the crow flies.
Troll over to the 82 and then work the ledge up toward the 84....plenty of nice blues and maybe some rock.
