We saw some chick on a silver Ducati 900SS, too. Sorry, no pics of that.
She had a full-face helmet on and blue jeans and such so you didn't miss anything.
Her hair was flowing out from under the helmet.
I think it was a 900SS. I did not get a good look at it. She stopped only briefly at the overlook before turning around and going on the downhill portion of the lap.
