Ranger Bill is remembering a few years ago, when they had so much snow up at Knotty Pine, from Thanksgiving right through to New Years Day. It got pretty cold at times, with the snow piling up, but then along came the middle of January, and the temperature climbed to sixty degrees! In a few days, all of the snow and ice had gone down the sewers and away. It was caused by a warm wind - something which is feared in Knotty Pine, and soon you'll know why when you hear today's story!
