Yea, I only get out in cold weather a couple times a year. I have a theory that maybe burying them in snow at night may insulate them enough to keep above freezing... Im not sure though. Heading out for a short hike here in a week and a half. The extended forecast looks to be into the single digits overnight and highs in the teens to maybe low 20's. Just thought I'd ask those of you that get out in this weather more frequently.
