Does anyone know what the dividing lines are to allow conceal carry while kayaking on the Potomac? I have a NC CCW, which is honored in Virginia, but DC is Marxist territory. Am I OK on the water in this case, as long as I don't make landfall on their commie country? Also, who owns the bridges, and there are a number of islands as well (Roosevelt Island comes to mind). I enjoy kayaking, and the Potomac is a nice venture, but I also kayak camp, and feel that I should be able to carry in this case, but want to make sure I'm not taken prisoner...
