Sunburn Nose, Suburb Ride

Why would I have sunburn in the middle of the bleak and cold winter?

If you recall, yesterday was a beautiful sunny day, with a clear blue sky. M and I went with Matt and Loren on a long bike ride out to the suburbs to Loren's parents' house. We rode from Bloomfield to Natrona Heights and back - about 40 miles. The temperatures were brisk - 19 degrees when we left. I had to wrap my feet in plastic bags to keep them from freezing in the wind. Does anyone know if the Highland Park bridge is in the City of Pittsburgh? I plan to call 311 today to report that the sidewalk is treacherous and to find out what it would take to get the city to salt some of these public walkways.
