I have been in the situation shooting a deer right on a boundary. I know how easy it is to fall into that trap. I shot a deer southwest of Meeker in a little depression called Indian Valley. It was a nice 4 point muley and where I shot it was perfectly legal.
However, I was then in a quandary because the buck wandered maybe 15 feet and died right on private property of a ranch owner who was harassing hunters who insisted on hunting that patch of public property. I had a choice back then, pay a $500.00 ticket for not retrieving the carcass or paying a $50.00 trespass fine. At the time, there was no exception for the $500 ticket if the animal died on private property. I opted to pay the $50.00 trespass fine. I did kinda see a bit of karma. The sheriff issued that rancher a summons for violating a court order when he locked the gates to the road which was under court orders to be open for public access.
The temptation is great, but now I will not hunt close to private property unless I am confident I can drop it or positive that it will wander further onto public property. I hunt like Randy. If I wound an animal and can't retrieve it for any reason, my hunt is done. That is just plain ethics that I put on myself.
I am 65 now and have been hunting practically every year since I turned 16 except while I was in the Marine Corps, so I have knocked down a lot of deer and antelope over the years. I have only not retrieved one that I wounded and not found after it crossed onto another farmer's land and I could not relocate him after I got permission to go get him. This situation is likely to come up with just about everyone if they hunt long enough.
