Does anyone know if there is a place in Southern Maryland that rents outdoor sports equipment for group events, such as a volleyball set, tug-of-war rope, potato sacks for racing, etc. When I've used a state park before, they rented this kind of stuff out, but I'm having something similar at home. Any ideas?

if your a retired guy from the navy, Pax river MWR has seabags full of stuff at MWR you can check out, not sure what the cost is
