The Gravity Powered Vehicle Association has regular wheel to wheel race events and speed trials
on the hill from the Palm Springs Aerial Tramway.
They use pedal bike frames and motorcycle type fairings for the partial streamlined class.
Their lay down class is like a skateboard with stand up, lay down head first , and lay down feet first.
If it will go from here to there, somebody has the fastest, and it ain't for the soft hearted.
The speed "Open Road in Traffic" record for the Luge Board was a carefully guarded secret and only listed
as "Pending Ratification" until the CHP testified in court and the ticket was ratified for speed down Cajon Pass.
And as Ack mentioned, I am listed as the "Unlimited Bowling Ball" record holder.
The stiff sentance, more than the speed will keep the attenpts to beat it to a minimum.
I know I did.
They really made it hard for the next guy really fast.
I helped them with the rules and timing equipment for the permitted events, the others were private time efforts.
