Hi Patrick, thanks and a great new year to you.
I suppose the "mule" deer could explain the hunters confusion---ookkkkkkkkkk!
Maybe during these hunter ed courses they make people take nowdays plastic identification cards could be handed out with common animals, farm animals, humans, vehicles etc represented so as to aid the hunter in identification, kinda like the old spotter cards used by the public back in WWII so they could identify the type aircraft that was about to blow them to bits.
