My 2 cents before I leave the country for a bit...too far to feel the flames
The solution seems simple. IF it's about socializing, charity and enjoying the people, then leave the trophys and the judgnig at the store where you bought them. Get together like we do in Austin, laugh, drink and enjoy yourselves. You guys didn't know it but there has been a contest in Austin every year...I win every year (even the year before my car was done) because I'm the judge...I just keep forgeting to tell you guys about it
NOW, if it's billed as a "judged" car show just make sure everyone plays by the same rules. If it's a driving class, better have some miles on it. IF it's a show class...better not have any dirt on it.
I personally like the shows that are about people better than the ones about trophys so those are the ones I usually attend because they are more fun.
Matt if you are going to color outside the lines let me bring my niece up there. She's 5 and has learned to color in the lines pretty well.
