Saturday I went on an hour and a half bike ride - 22 miles. From my home to the airport and back (okay, at the other end there was frozen yogurt involved (double okay - frozen yogurt is basically a fruit & candy delivery vehicle)). I love the move through space, the sustained dumb exertion, thinking snide things about passersby, singing quietly during solitary stretches until slightly winded.
Weather was great. There's only a 40 block stretch shared with vehicles. While on guard, it's always heartening to think of the number of people who COULD mow me over and choose not to. Strain and adverse conditions usually make me laugh.
A bit of daydreaming, a lot of reflection, but never, ever any particular big-picture resolve.
