A friend and I ride Piuma Canyon Road, Schueren, and Stunt Rd. in the Santa Monica Mountains overlooking Malibu California. My friend is riding his 2002 Moto Guzzi V11 Scura that he just purchased. I am following on my wife's 2006 Triumph Bonneville T100. It was a very blustery day so the sound is not as clean as usual with the GoPro Hero HD camera.
