Some mornings start out calm and clear...
and I ride south with the wind at my back.
Others are shrouded in fog and three friends in Golden Gate wake
to hang in the clouds.
But inevitably on the same misty day, I am suddenly grounded,riding right over a shard of glass in The Mission.
I puncture the back tube (why is it ALWAYS the back tube!),
and manage to change the tube before the sky really opens up.
Just a little grease...
...deepening the biker's lifeline.
