I had my 4th commute of the year. It was a cold morning (27F) and a cold/breezy ride home. I got new tires on my commuter and had tire liners put in. For my first ride, I thought I was dragging a trailer with brakes on. I couldn't believe the drag. And, on my ride home, I dislodged my pannier and it flipped off the rack when I hit a pot hole. I didn't know it had flipped off until a guy in a truck pulled along side me and told my I lost my bag. I rode back up the road and couldn't find it. I was bummed. Then he honked at me from across the road and when I road over to him, he held it up. He said it lodged under a car and he was able to catch the driver and they got the bag out. It was a total lost. But, I had my new showers pass jacket in it that wasn't too badly damaged. Several other items, though, are no longer useable. Oh well. I can tell I didn't spend enough time on the trainer this winter....
