RE: elk DIY follow-up / spike camp?
Bag, pad and tent are a minimum along with food/cooking material. Remember if you shoot something, it's all extra stuff to carry out.
We hiked in 7-8 miles and back out again each day rather than camp in. In retrospect it cost us some good hunting hours. But we carried lighter packs over a nasty pass and when we did shoot something it was more convenient when packing it out.
I think next time we will hire horses to pack in our camp and pick us up. Best of both worlds.
