I'll be down on the Cape a LOT this summer... So I'll be bringing my gear.
Then you should be checking out Camp Paintball in Kingston.
A very short trip up 3 from the Cape.
Home field of the Scenario Geeks from PP I, II, III and soon IV.
Home field of the mass chapter of the Marshals.
Best field in New England.
