Cold and windy weather last Friday couldn’t stop Josiah Clark, Michael Park, and I from hopping on our bikes and exploring the SF Presidio, crossing the Golden Gate Bridge, and riding into the Marin Headlands.  High school phenom Logan Kahle joined along for the early afternoon.  Not the most diverse day, but we did manage […]
