It started snowing Tuesday afternoon and stopped by Wednesday morning, though it got pretty cold through the night. I biked from North Cambridge to Back Bay in Boston in a period of pretty high snow fall, and the cities of Cambridge were keeping up pretty well with Mass. Ave., at least. I took my bike on the T back to Forest Hills and froze riding the last mile home. The streets were clear when I biked to work late Wednesday morning in 10F, and the paths were all plowed, too.

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