Trail running..

Did the trail thing this morning... it was very cold but once I started running, I felt fine. The ground was pretty hard though. Also saw another runner (older guy, thin build, wearing a red GAP hoodie, sunglasses, no distinguishing facial features, maybe 5 8"?) on the trail. Had seem him on Breiel earlier running and noted him. Felt somewhat odd to see someone else running, and brought back memories of events at PSU many years ago, but all was well.
