I'd like to know what laws there are regarding transporting firearms accross state lines, ie to Ohio, West Virginia, or New York (NOT NYC). I don't even wanna think about Maryland, but info there would help too. Say I happen to have a pistol or rifle in my truck and feel like driving into Ohio, since it's nearby. Or what about on vacation to New York? Would I need to take them down? Would it even be legal that way? And another question is whether it would be legal to carry a shotgun in one's backpack while hiking in the Adirondacks, for protection against rabid animals or bears.
