PA/NJ/DE/MD CGs with sites right on a lake or shoreline

Thanks Spoon for all that great info. I looked on line for reservations at Assateague, and all the electric sites are booked through October. I may try the other CG you suggested.

Breezy Point is about 3:15 from my house. It's also about a hour to drive and take the Metro into DC, which we like to visit also. I'll have to see if they have any available sites later in July or August.
