I have a hard time staying warm, but hubby and I used to enjoy winter camping quite often when it was just the two of us. Now that we have little kids, our winter camping consists of skiing in to a yurt or forest service rustic cabin that come equipped with a little wood stove. The prospect of keeping the littles dry, warm, and entertained in a tent during the many hours of darkness is a little daunting, but in a yurt or cabin we have a fantastic time. The last time we did this, it was about 20 below zero F when we skied in after dark, but the kids were well bundled in the enclosed trailer that we pull behind our skis, with hot water bottles. The trail in was just a couple of miles so they didn't have time to get too cold, and the yurt warmed up quickly once we got the fire started. We cooked dinner, played games, and had a cozy night (as long as we got up to feed the fire regularly). The next day we went for a ski before heading out, and saw a moose and dozens of trumpeter swans, and lots of animal tracks. It was amazing. Yep, winter camping can be lovely.
