Zay, I hate that you lost that deer but at the same time, you did the right thing by not knowingly just going onto someone else's property without permission. At the same time, whomever owns that other property, should have granted you permission to attempt to retrieve your deer if you asked them. I know I would have not only allowed you access but gone and helped you look. Hate it for you. There will be other big bucks. If you hunt long enough, you'll lose a few for various reasons.
