It sounds like a great idea as long as you don't think about it too much. Give some thought to "living off the land" in the western mountains during Nov., Dec., Jan., Feb. and March. Living can get pretty skinny pretty quick. I lived in Billings MT. in 1973&74 and back-packed extensively and hunted Bighorn Sheep in the o.t.c. permit areas in the Absaroka/Beartooth Wilderness Area northeast of Yellowstone Park. I treasure memories of the incredibly rugged and beautiful wilderness, the solitude and the challenge of the hunt. I will also shamelessly admit that after as long as nine days living out of a backpack, getting to my parked 4 w.d. truck, starting that gasoline engine, driving down that dirt then gravel and lastly that paved road to home was pretty nice. And that first hot meal at home was tied with the hot shower for just plain wonderful.
