ride this sunday: 2-part (1 easy, 1 long)

Part 1: Sunday Streets (http://sundaystreetssf.com/?page_id=470) route from the ballpark at 4th and King (meet there at 10:30am) down to the Bayview Opera House. Part 2: A ride as far south as we can along the Bay Trail (a separate bike path or lane some places, but also riding on the street many places). Maybe to the airport or farther to Foster City/Belmont (once we pass the airport it’s an amazing section of swampy marshes and mostly paved, car-free riding). I’m thinking an abridged version of this general route: http://www.bikely.com/maps/bike-path/San-Francisco-to-Sunnyvale
