I don't think it's a stupid rule (law) to tag your deer immediately. I have never had the tag fall off when dragging a deer out of the woods. I simply use a large safety pin that holds the tag and pin it thru the ear of the deer. Who's to say that anyone is gonna tag their deer on the way to the station? If you must tag immediately, there is no doubt the deer is now legal. Dragging a deer out of the NH deer woods without a tag may be interpreted as poaching. Tag it right away and there is never a question or doubt.
