We always tap the Ted Nugent "Give 'em the BLADE!!" sticker on the lockers adjacent to the cabin door on our way out. Have been known to drive back and tap it after forgetting.

After the kill I always put a small cedar branch in the deer's mouth and offer thanks to God for the life of the animal that will now give life to me and my family. ( I think I read that in an old Fred Bear book, it comes from an old German deer hunting tradition. I thought it was cool so I adopted it myself.)
