Sounds like a great ride. We had similar weather in Maryland. While riding on Braddock Heights west of Frederick, Maryland, the LCD temperature display reached 72 degrees Fahrenheit with plenty of sunshine, although temps were more typically in the 66 to 68 degree range. Spectacular for a hundred mile ride in December around here!
Now we have a winter weather advisory starting at 1:00 AM, but the riding weather was great while it lasted.
