A walker's sketchbook of San Francisco

Color-illustrated sketches made while the author walked on every street in San Francisco. The book also includes 20 walking routes with descriptions and hand-drawn maps. The author writes in her introduction, " I set out Jan 1, 2015 with the best maps I could gather and began to walk. I finished in mid-November, having wlaked 2,289 streets and alleys, all that I could find, over 700 miles."
