First, the thrill of being in God's creation. For example, there is nothing like hearing birds chirping and seeing the sun come over the hills. Hunting season is in the fall, and there is a cool breeze and colorful leaves falling through the air. You feel like you're getting a little glimpse of heaven.
Second, the memories will stick with you forever. For example, if you go hunting with your grandparents and see a little squirrel. It is a good time to make memories with people that aren't always going to be on earth with you.
