Evidence of climate change on a sun-splashed rock

Wally Vait has a good eye for such things, so I'm not surprised that during a hike Saturday on the North Central Railroad Trail in Freeland, he spotted an Eastern garter snake on a sun-splashed rock. The question: What was it doing there, after one of the coldest Novembers on record, and with the winter solstice two weeks away?
