cause you;'re too lazy and stupid to carry what you should have? then carry a rental satellite phone, dummy! if you are too lazy/stupid to have the right gear, then HOW will you know all the things you'll need to know, so as to use them in time to save yourself (4 seasons, anywhere you might be)? it's a farcial assumption. you'd damned well BETTER have 10 lbs of gear, and water (or that satellite phone) if you get more than crawling distance from a vehicle or a building, especially in the mountains or in cold months/terrain. you are lugging around 20-80 lbs of blubber NOW, so why can't you carry 10 lbs of essential gear and water?
