Thanks for the input, I guess I'll have to learn to deal with some cold. I found a 30 degree bag made by Columbia that weighs 3 lbs, thought I might try it out. It's at the Campmor cite. It's odd, that's the closest camping store to where I live. Maybe I should take a trip there soon. Anyway, the bag is filled with ThermalC synthetic insulation, not sure how nice that is. But, it's about the least expensive bag I could find that weighs an acceptable amount. The places I've been going lately are up in the Mountains of West Virginia. It's not too cold, around 40 degrees each night at the moment, and soon it will be warmer so I will be able to take my summer bag. Maybe I should just take an extra shirt. Thanks for the help folks.
