Yah, I saw a "handicap" outfit at the SoCal Griffith Park sidecar rally, the rig totally operated from the car! Doug Bingham, Sidestrider.com, is considered "Mr. Sidecar" and has been organizing this biggest sidecar rally on the west coast for years. Funny thing is that so many 2-wheel motorcyclists come to the sidecar rally that there's not enough parking for them! It's interesting to walk thru the 2-wheelers parking area just to see their rigs, vintage, classic, and modern
Doug originally setup my Kawasaki 1500 outfit for it's previous owner, and I go back to Doug when I need to. (not my GZ250 yet)
