On Wednesday night, the snow started as I was biking home through Brookline Village. After I cooked and ate dinner, there was enough snow to shovel before I went to bed. At that point it was the fluffiest snow that has fallen on Boston this winter. Thursday morning, there were another two inches of snow which was getting softand mushy in the sun, and it was a bit harder to shovel. The paths I took were well-plowed, with lots of bare pavement, no ice, and no problems on the occasionally unplowed sections with my studded snow tires.

Please send updates and reports on the conditions of other paths in Massachusetts to Jessica Mink.
