In my few rehab rides so far I've noticed something that had apparently escaped me before. From the expressions on the faces of oncoming riders they aren't enjoying the ride.
I saw expressions of intense, this is a duty, concentration. I saw expressions of near exhaustion. I saw expressions of boredom. But, I didn't see many of joy, or satisfaction, or peace, or even just pleasure. Probably the happiest expression was on the face of a guy wearing a winter coat, wih a big backpack, with a radio hooked to his handlebars as he leisurely looked for a place to spend the night.
