I think it is great TnMountains, that you donate game.
Some states have stopped that practice, apparently thinking its too much of a pain to certify the meat. Pennsylvania used to accept game, and, new roadkills, as long as it was killed and cleaned within a certain time period. (also, in Pa., if you hit a deer with your vehicle, you can legally keep it for yourself, you just have to report it).
About 5 years ago, we had just such an incident, and the carcass was refused, with the explanation that they didn't have the resources to certify the meat.
What a waste, to be sure. The car that hit it was directly in front of us, and when we called the agency, the animal was still alive (broke its back).
The guy came to the scene, shot it, and drug it off the road. About a week later, a special truck had to pick it up. (we were not allowed to take it, since we had not hit it - but I'd do that whole thing differently today).
In the west, here - killing an animal by mistake is not the big issue - its the wasting of meat. A 25 dollar fine for killing an animal accidentally (like a doe instead of a buck), you get another license, and they take the meat. Leave the meat and - you are going to jail - and it is a felony.
It wasn't that many years ago that if it wasn't for deer, our protein intake would have been sadly lacking. And we never kill anything that we will not eat. (no killing things just to put them up on a wall, or just to kill them) - Sorry, but I just lied - the exception is poisonous snakes, especially if they are near my house.
