When the first light climbed over the ridge line, the two sleeping bags beside me started twitching like worms trying to burrow back underground. I cracked open the hood of my own bag and found a thin skin of frost had formed across it overnight, that alone was reason enough to stay put a little longer. 

As the sun’s beam broke the horizon to the east, the two sleeping bags spread out next to me began to wiggle like earthworms trying to escape back into the ground. As I unzipped the hood of my sleeping bag, the thin crust of frost that had formed over the top made it easy to remain inside. The forecast had called for lows in the 20’s, and I didn’t need a thermometer to know it was cold.
