I live ,as most of us must,in an urban environment. I can get in a car and be in desert, forest or mountain and on the ocean within an hour. People freeze,drown or die of exposure in view of the twinkling lights of Los Angeles regulary. It doesn't take a whole lot of planning to walk 100 feet off a roadside driving to Vegas for the weekend and break a leg, get disoriented or left behind. My avocation and vocation can take me off the beaten path on short notice. So yes, my psk is in my pocket.
