For me, I got tired of wasting all my energy hiking in-and-out everyday. I also found that I was spending the very best daylight hours to hear bugles (the first and the last) hiking and not really hunting. So I invested in a solid but lightweight bivy set up and I now hunt off my back. I pack camp, 3-8 days of food, water purification, etc. when I find elk, I hunt them. When it starts getting dark, I make camp, eat dinner and rack out less than an hour after dark. And, I can sleep till about an hour before legal, enjoy a hot breakfast, and still break camp before shooting light. But I don’t have to be moving b/c I’m already where they are (or close to it). I’ll never go back (trailhead). I can remember feeling that gnawing anxiety every afternoon, pushing me towards the truck to avoid hours of hiking in the dark. It’s so much more relaxing now, b/c I don’t ever have anywhere to be besides where I am. Also, if you put an elk down at dark, once you get him into game bags, you are done for the night. Move the meat away from the gut pile, then Go up the ridge a bit and make camp. Get a good nights rest and start packing in the morning.
