I'm the "kitchen sink" type. I try to take everything I may possibly need. Extra gloves, hat, and batteries for everything. Paper towels and cleaning gloves are handy. You never know when you may need rope or electrical tape. (I'd take duct tape but it's a little bulky) If I'm rifle hunting, I make sure to bring a lens pen just in case I need to clean my scope. Water and some snacks are also good to have. I'm 25 and in pretty good shape so weight isn't much of a concern for me. I like hunting clothes with lots of big pockets so if I have to track a deer I can put the essentials in my pockets and leave my pack at my stand.
