The only way we learn to carry only what we need is to carry what WE THINK WE NEED, and then, at the end of the day, take an inventory of all the stuff we didn't use! Re think what you want to haul around tommorrow, leave the other stuff in your car or truck, and try again. After a few trips into the woods or fields, you get a pretty good idea of what it is you need to take with you and what you DON'T NEED. There is no magic formula for all hunting, all locations, all weather conditions. Its always nice to listen to what others do without, only because it helps you make a mental inventory of what you take with you, and maybe decided, after years of taking something along, that you really don't need it in the field. For instance, I carry an 8 foot length of 1/2 inch nylon rope in my day pack. I used it to help get my first deer up the steep portion of a ravine she managed to get to the bottom of. I have not hunted that same kind of country for deer since, but I have carried it into the field every year I have hunted since then. It probably needs to be left in the truck, these years. But, It surely was the right tool to have when I needed it. I do keep a plastic rain suit in the bag, even though its worthless in thorn country. It works as a great wind breaker, when the temperature drops, and it save my life one Fall when the bottom the thermometer dropped out while I was a couple of miles from my car.I suppose it could find its way into one of my large game vest pockets, but the nice thing about carrying a day pack is that I can leave stuff like this in it all the time, and its ready to go by just slinging the pack over my shoulders. My survival gear, my compass, several ways to make fire, an extra knife, a short honing stone, maps, they are all in that day pack, ready to go. Now, when I am field hunting for birds, everything goes in my pockets. At most, I may have to drag along a seat to use when hunting dove.
