That's about the best statement I've heard you come up with Ray, my understanding is that generally Historic and Classic racing is for the vehicle owner to go out and enjoy his(or her) car and drive at a pace they are comfortable with having some fun, like a Sunday game of golf! because after all there's nothing left to prove racing an old car. I have mentioned my Monterey experiences in the past, some years they have good size spectators other years none, but the event still carrys on regardless and the racer attendance is always the same. How do they make $$$ and run it, well the racer always pays that's how.
Another interesting take and I mentioned this over on a FB page, both Timaru and Scope had huge crowds(so I'm told) they had almost the very same classes that raced at Quinn's Festival(2 weeks prior to Timaru) and the Taupo GP were no one bothered to turned up, is it a North South thing? is it because there's less to do down south and too much to do up north? after all the amount of events, concerts, etc on up here is mind boggling.
