Now that the LBS employees know me by name, I often see them (in full spandex & road racer garb) while I'm out exercising. They always greet me by name as they blow by... I'm amused at their kit and often speed up to their pace for a while just to see if I can.
The biggest character I encounter is a bald headed guy that's my weight, but about a foot shorter than I. He rides an OLD and HEAVY MTB on the paved roads & bicycle paths around the lakes. His average speed is about 25-30 mph! He speaks to nobody, won't reply to greetings, and leaves everybody else in his dust. I don't know how he does it, but I see him regularly. Wish I could match his speed even with my red racer!
