yes, but so is opening yer eyes and looking around. a lot. a whole lot. i was VERY young my 1st winter out west and a bud of mine and i were up at a trailhead and he pulls out a map and guidebook. i look at him and asked him what the fuck do we need those for? we can see everything right from here. isn't very difficult if you learn to or have an eye for terrain features/angles and such.
and why anyone would hop on a skinner that's already there is beyond me. choose yer own adventure for christs sake. plenty o room to roam and avoid other humans in most places in the mtns.
