Free: Contests & Raffles.
Well since you already have a pack on id say a range finder, windicator ( little bottle of powder) and some elk calls if that's what your hunting. That's really all I've ever "needed" as far as the hunting part. The rest of the trip has a lot more variables
Stone!!lol one thing I can tell you won't go in my packs is rocks for gods sake
Surprised i haven't seen headlamp/flashlights (w/ extra batteries of course) on these lists.
