Just the other day I told Todd the story of how I got into land speed racing, now that you mention the topic, and I expect my story is just as strange (to the outsider) as the next racer's story. Ask me, out there, this summer.
As for what ought to be in your book -- I agree that what ought to be there is accuracy first and foremost, so that the folks who do know the correct information about any particular item -- don't see your erroneously-stated fact and instantly lose faith in the rest of the book. I'll here and now offer to help with proofreading and spell-checking, because no matter how much folks protest -- well-written and spelled literature is best. "Spell Check" programs are only as good as the training of the geek that writes the program -- which, it seems, doesn't promise well.
And finally for this post -- here's a great photo to show the wide variations you'll find out there. I've referred to it as "Nancy in fast company". Roadster, Burkdoll's 'liner, and my sweetheart at the line, with Jim Jensen (the starter) doing what he does so well -- get us going, one at a time.
