It started snowing Monday morning and snowed till evening, with maybe a bit more later Monday night. When I biked to work everything was pretty clear, but by the time I headed home in the evening, there were a couple of inches of snow on everything. The deeper, wetter snow froze during the night, making Tuesday's trip slipperier. Boston wins the cleanest path award this time for the Jamaicaway path which was clearest from Tuesday morning through Wednesday night. There seem to be a lot more cyclists out after this snow that I've ever seen before.

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