Snow began early tonight, and added up to 3-4 inches more (than was left from Friday's storm) --- it never truly stopped snowing yesterday though (was quite windy, which kept the greenhouse clear).  If I'd thought about it, I probably wouldn't have left the pump on yesterday (because it was completely overcast and snowing) but the numbers tell an interesting tale (warming up the water tank 4 degrees from 44 to 48, yet the temp in the gh never went above 38).  Today I did unplug the pump, but I'm also intentionally leaving the 3" of snow on the gh until morning (so there's really no solar radiation making it through that blanket of snow, it's quite dark in there even in daylight).  The outside temp rose through the night (and also through the day today, look to tomorrow's numbers to see that (and the effect of my blanket of snow)).

good skiing, a little icy early, but it was pretty fun and I got in a full 2 hours until the muscles were tired enough to make me think quitting would be a good idea
