I have been a spectator to that event., and that's okay.
As an owner of two showcars...I would NOT take them. They close down the street and park the cars all along. They are parked too close together, and when you add that to the people walking their dogs, pushing the strollers, the chain wallets....need I say more?
A number of years ago, I had an interest in going (before I know what I know now) and was told that the judging would be done as you register...then if they think you have a car worth looking at...they will find it at the show.
