This is the way I go to visit my sister. I avoid major streets when possible and crossing arterials is aided by traffic lights most of the time. Road surface on 4th street is poor. Loop detectors for bikes at Wilton would be helpful. Del Valle at Fairfax is blocked to cars, but accessible to bikes. Could be even easier. Crossing San Vicente is actually not as easy as it may look due to the large median in the center of the roadway.by Cbogart
