Very often, if you feel cold, a drink of even cold water will quickly warm things up. Try to allow yourself some time to wander after camp is set. Enjoy the views and the tracks of deer wandering to feed on birch shoots, snowshoe hares, bobcats, fishers, grouse, foxes, and the ubiquitous red squirrels and mice. The only thing you generally won't see is other human beings. When winter camping, you pretty much have the world to yourself.
Dinner consists of a simple, calorie-rich stew.
Usually by the time you've finished cooking, eating, and preparing water bottles and thermoses for the evening, it's time to remove boots and outer clothing and take to the comfort of sleeping bags inside the tent. Well, a headlamp helps. When alone, you can read or toot on a harmonica. Chances are, however, that you'll find yourself ready for sleep long before it's time for the late show. Sleep comes easily in a warm sleeping bag after a good meal and a day of hiking in the cold.
