I am doing something similar thursday night. Although, I AM goona cheat. I will have a BD megamid with me, a stove, and my 0* sleeping bag. My intent isnt to "survive", but, to try out my bag (I havent had a good chance to try it in real cold conditions). I will, however, practice my firemaking skills, and, perhaps water boiling (if I can get through the ice).
I am taking my nephew shelter building on saturday. I just ordered him his own Mora knife <img src="/images/graemlins/smile.gif" alt="" />. I plan on getting some video of thrusday, and pics + vids for this weekend. Stay tuned!
