Thanks to all the posters. I don't have enough knowledge to contribute to the tracking discussions, but I can at least contribute to the obs. May have picked up an inch overnight, and it is steady light snow this morning. There is enough of a glaze atop the snow that our 7 lb. dog can walk across most of it without sinking if she doesn't jump. This has been a wonderful event for me. Reminded me of my days in Kansas City and Louisville, KY.
