This topic has me a bit stirred up.If I shoot an animal on property that is mine or that I have permission to hunt on and it expires on someone elses property I will retrieve it.This isn't europe where the landowner owns the game.Any landowner with any modicum of sense would never have a problem with that.
It is all about conduct if someone is a known poacher or has trepassed previously on you property than they don't deserve that courtesy.
To think otherwise is assinine,anyone with any amount of decency would help the other hunter transport the animal to where ever they were going.If I knew that the landowner was an idiot,I would plan accordingly,I would retrieve the animal and they would never have known I was there.
