If by "firsthand" have I been directly involved, no. I do know people who have been gigged for carrying long guns on Clarks Hill and Russell. As far as I know they all had to go back to their vehicle and leave it there.
Those border lakes are extra tricky because SC has different rules about having a gun in a boat, the SC DNR strictly enforces their rules, and you have to know where the state line is in the middle of a 79,000 acre lake. If you are going from Point A in GA to Point B in Georgia, but cross the state line, you are subject to SC while in SC.
Good to know.
Anyone else know anyone busted for carrying concealed on Corp land?
