Tough going today, left the house 0 degrees F, clothing layered up, computer froze and had no display, right shifter would only shift up so I rode the entire ride in the big ring. I took my panniers off before I left to lighten the load. Traffic was light but the car windshields were all iced up causing a few uncomfortably close motorists. I was still toasty in my clothing when I arrived at work, my average speed 13.2 mph for 18.5 miles.
