Doc Wong’s CPR and First Aid for Motorcyclists class . All Doc Wong clinics are educational, fun, and free. They are put on by a pillar of the riding community, Doctor Harry Wong. Night classes take place in Doc Wong’s Redwood City office, and Sunday rides start at the office with a talk and are followed by a four hour ride through the hills. The Doc requests that you email him or call his office to let them know you will be attending a session, and we recommend checking his website as well for further information on his different classes. Confirm by emailing email@example.com or calling 650-365-7775.
