I see so many of these hunters on T.V. carrying a backpack while hunting whitetails and I can't figure out what all they need to make it through the day that they would have to have a backpack to carry it in. I always have a extra release,flashlight,grunt call,can call, gutting knife,gloves and facemask,limb saw, rangefinder and all of that fits into a 7 pocket fannypack. So I'm wondering if you guys wear a fannypack or backpack? And if you wear a backpack what all is in it?
