Only a 20 miler down to the LBS- 10 miles each way but into a headwind that was cool. Decided to push it a bit and paid for it. At one point I saw a bike???? in front of me and chased it. Could not catch it and it must have been a casual rider due to the upright stance of the rider. Chased it for 5 miles and could not get any closer. Then a set of traffic lights and it was not a bike. It was one of the low powered engine propelled scooters that abound over here. The rider must have had just as much trouble with the headwind and the upright stance as I did- and I must get new glasses.
