Hi JC-1, Hopefully the more experienced people will jump in and help us, but here is what I'm hearing and learning so far;
Carrying game: Some folk use "game bags" or "game vests" inquire at your local sport store. However, Some folk leave game exposed, tied to or pierced on a stick or pike or something like that (after gutting) to help it cool down. I'm told that dissipating the natural body heat is very important to preserve a good taste in the meat. Here in NJ, they want us to keep our harvested animals out of sight when possible to avoid offending non-hunters.
I'm also told that gutting the game as soon as possible, especially when you think you have hit the animal in the stomach or intestines or pierced the urine bladder etc, will mean a better tasting meal. If you don't gut and clean asap, the meat will be basicly "marinating" in urine and feces and will be more "gamey" tasting.
Of course you will be hunting birds and different rules might apply? but I'm sure there are accomplished hunters out there that will soon post here.
Good hunting! Safety first!
