On Sunday night, my flight to Illinois from Boston for my uncle's funeral was delayed by three hours due to a snowstorm in Chicago, and my flight back to Boston on Monday night was delayed when that same storm hit Boston. By the time I biked to work on Tuesday morning, the skies were blue and the sun had helped clear the paths.

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