RE: Sleeping Bags
Sierra Trading Post has some 0 degree bags for $44 - they've got one that goes to -5. I've got a 0 bag and it works for tent camping in the winter in N. Idaho. It's often too warm and I end up unzipping it. A good pad really helps insulate you - get one of those "you unroll it and it inflates" pads and you'll be comfortable. Sierra Trading Post is a great company to deal with - no questions on returns and if they've got what you want the prices are usually the best.
