Thanks for the tip Chris, I will look for that book. A good
friend of mine worked on the GT-40 program in it's hey day
too. It would make a good read for me and a very special
present for him if he does not have a copy. Like all racers
i am sure he wa to busy racing to do much else. That's the
same reason I have so few photos of cars I raced. I am not a
driver but an engineer and love the design and tuning
aspects of racing. The only issue I have with Bonneville is
i want to be at the start to make sure that car gets warmed
up properly and gets off ok and also be at the 4 to hear it
go by to give the tune up a final check..LOL But if I could
get to the 4 before the car then maybe racing the wrong
vehicle.. I bet I will be the only one in the old folks home
listening to sound track of 'Grand prix' instead of old big
band music LOL...
Dave ( who has been haunted by that certain sound for over
40 years)
 BTW did you race at Lake Gardnier in '95 your name sounds
very familiar...
