Mountains are out for running to. Get behind a dually with 5th wheel that busted an axle and your up shit's creek. Never mind how good physical shape you're in it's the others in the group i doubt are going to start humping gear over the peaks vs driving to them. Combine this with a short grow season vs the plains and your food sustainability once game animals become thinned, gets limited.

Power outages, natural disasters are always a possibility and having a good phone tree/ lines of communication is a must have for anyone.
Are there some i would include that are not too gun savvy, absolutely as their skill set trumps gun knowledge.
