It's threads like this on THR that caused the following to occur to me.
I'm a civilian -- but I went to a military base to visit a buddy a state or two away. Knowing stuff like this I checked my firearms in the house to make sure they were all accounted for. Good, no possible way for a gun to be in my car when I depart.
I get almost all the way there and start realizing that I didn't scan my hidden compartment in the trunk for ammo. Fits boxes of 7.62x54R rather snuggly. So, I get gas and check. Nothing... then I moved a towel -- BINGO! My idiot self finds a box of 100 rounds of 20 gauge target loads. I've got no idea if this is going to be legal to take on base. I ponder just how likely it is dogs would alert on my car with some shotgun shells in there -- then I realize that I've had weapons in that trunk many many many times that have just been fired. Residue is probably everywhere. If they're looking, they'll alert.
Scan the parking lot, wondering if I can just give away a box of 20 gauge shells to anybody. That'd be what I prefer honestly. I'm in IL though so I have no idea what the legality is. I don't see anybody with an NRA bumper sticker, or Molon Labe hat, but found a guy with a TN license plate on an RV. Didn't even ask -- no idea how that'd be received.
Buggered down the expressway pondering my options... I don't know of any way of SAFELY just throwing the stuff away... so I guess I'll hide it somewhere and pick it back up.
Pull off the expressway in a town that has absolutely NOTHING in it... lots of farming country. Ventured about 6 miles off the beaten path (and that path wasn't very beaten) and dumped it on the side of the road for the day. I'd be back tomorrow to pick it up -- looked like a dry spot, so it probably wouldn't ruin it. It was raining though, so I figure some of them went dead -- we'll find out someday.
Found it the next day on the way back. I brought back passengers this time, and they all got a kick out of the story when I pulled off the expressway in the middle of nowhere.
