Very foggy this morning, not too cold though lower 30's or so. I was pretty lit up and wore a safety vest. About 1 car in ten was running dark.

Bike just setting in hallway and employee comes in to my office to say the tire was hissing. Broken valve stem. What a mess. CHanging a tube after two months of winter sludge, and the knobby studs. At least it didn't happen an hour later when I'll be on the road.
