A hunting buddy and I were walking in to our stands on opening day 3 or 4 years ago. We got to the point where we split ways, about 1/4 mile from the truck, and he says "Oh crap". Naturally I respond with "what?". "I forgot my bow" No joke. His bow.
My biggest thing has been forgeting my pull rope. I hope I've learned but I'm affraid maybe I havn't since I've done it several times. Oh i forgot my release once too.
