Got to hang out with Smokey at the Induction ceremony for the International
Hall of fame thing.... What a character... seems he owned several
helicopters and as a Pilot he and I shared several stories....

Smokey Shouldn't have a Pilot's lic by the way... Damn man treated them
like he stole them.... (kidding obviously)  he hot rodded them just like
the cars and Motors over the years.... neat guy... and lots of fun... I
wanted to chat about cars.... and he was all about the Pilot thing... funny
conversations going 2 different ways but always forward....

again Carrol Shelby was the Presenter for Donald Healey and we spent the
evening Prior with him... in a small group.... pretty neat... 

Keith
