First and foremost you need to be in some kind half way decent physical shape, you could die out in them thar hills. higher elevations harder to breath, snow conditions make it harder to hike dem hills. So get to the gym or start walking alot of uphill walking, try to drop a few pounds weight is a killer too. Not trying to scare you just tryin gto inform you.....we are not as young as we used to be,,some of us would rather die beforewe would admit it....NO JOKE You have to be fit to play with mother nature
