I was a little cool in just shorts and short sleeve shirt, but at 57F and warming to 77, I couldn't resist. I had to leave about 10 minutes later than I like, but was able to keep a good pace and still made it to work on time. I felt light and fast with no extra clothing and averaged 17mph. Usual is more like 15.5 - 16.5.
Tomorrow should be a light traffic day as many are off for Good Friday. I work, but have Monday off instead.
