Winter Camping

I am on the verge of going on one of the most difficult and exciting experiences I have had. On the 30th I am heading out into the snowy and cold woods for a winter camping course. We'll be camping outside, in snow shelters, for eight days. I'll be gone for New Years, but hopefully it'll be worth it. I'm very nervous about losing fingers and toes to frostbite. I'm hoping to learn a lot, about winter camping and also about listening to my body and it's needs. This will be a fun yet hard course.
