I only had one minor injury from the cold. I tucked a hand warmer in my sock, as I've done a few times before when I can't get my feet warm at night. It worked its way up my sock and I woke up with a second-degree burn underneath. What surprises me more than the nasty red blisters cooked onto my ankle, is that I was so exhausted from hiking up snow covered mountains all day that it didn't even wake me up.
And the worst part is, I just realized I'm now a part of that group of idiots that have made it necessary to put warning labels on everything.
