Our snowfall yesterday morning quickly melted, but the frost was so heavy this morning that it looked like light snow. I passed drivers all along my route scraping the windows on their cars and warming up their engines. It was colder than I expected and my water bottle froze half-solid by the time I got to work. Should have worn my warmest gloves and my fingers were numb halfway through the ride. Hot coffee at my desk sure tastes good right now.
