f I timed it right, I’d make all the lights and speed down Folsom with no hands, the city a foggy blur I glided through on my commute into the office. But such mornings were rare. San Francisco is full of so much I didn’t want to miss. A freshly painted mural outside Philz Coffee on the corner of 24th Street; a mother zipping up her daughter’s purple jacket on the porch of a remodeled Victorian duplex; a bearded man singing a song I couldn’t catch into a glass-bottle microphone. I’d take in all I could as the tunnel of Chinese elms along the southern stretch of the street thinned out and I approached the 101 underpass. With cars rumbling overhead, I’d fix my gaze straight, toward the glass high-rises, and grip my handlebars tight as Folsom arced into SoMa.
