I don't know the specifics, but there is a D-Day Ohklahoma that is set on a Lake. Why a lake? Because ya' gotta storm the beaches from landing craft that take you inland. The whole thing is 3 days long, and I'm looking forward to next year when it happens again. There is even a contest to see who can make the most historically accurate paintball tank... and you have got to love that. Also, from what I remember, reproduction outfits of the various armies involved are optional wear for the scenario. Just so you know, the thing attracts over 6,000 paintballers annually.
