[quote=billstephenson I've found that it's mostly food and clothes that I need to work on right now. I've switched to dehydrated dinners, a "Cat Stove", and right now I'm sifting through what I really need to bring for clothes. [/quote]

An alternative approach to the excellent posts by WD and phat...

I save weight by bringing extra clothes and some other gear. Let me explain this counter-intuitive statement: I bring extra stuff in the car to the trailhead. That way, I don't have to stress about not having something I need. Then, when I see conditions (& weather) at the trailhead (how much snow is really on the ground, for example) I can just leave stuff in the car if I'm reasonably sure I won't need it. But it's there if it looks like conditions are worse than I had expected (or hoped).
