My worst frostbite was back in the 90s skiing at saddleback. It was 0F and wind was blowing. Got to the top and thought it was best to take the long three mile green trail down since it was sheltered. Without a face mask that didn't end well. Got to the bottom, went into the lodge and nose was white as a ghost. Had no feeling. Once it started warming, the pain was briefly brutal then just sore. Bought a face mask in the ski shop and skied a few more runs, but called it early. went to health center couple days later and they said it was 2nd degree frostbite. memories...
