Small amount or large, it all goes in and comes out the same way.
No truck, no ATV, no horse, not even a dog sled,It all goes in on my back.If I can't carry it, it doesn't go. (although on big/long hunts a few years ago I have been know to have a back-pack around 70+lbs)
I don't carry near that much now, but I do usually carry and extra waterbottle and/or thermos for my father since he can't carry like he used to and is too stubborn to admit he can't, etc)
