I found it hard to even think about doing all that when I broke through the ice on my sled last March. As soon as that water hit my body my adrenaline hit turbo and i just kicked and pulled across the breaking ice until I got out, and had all my gear and almost all my clothes off within seconds. I sat there in boxers and a t-shirt and wasn't even cold, but it was March, I can't imagine a cold February day brrrrrrrr.
