Is judging worth the outcome

There are a couple of organizations near me that do car shows. The shows turn out pretty nicely but the awards are all over the place. People's choice is probably pretty good but beyond that, not so much.... when the organization needs judges they turn to the guys that they know who know cars, members of the local Mustang club. Even as hard as those guys try, how much do you think they know about Mopars, Studebakers, Chevy pickups etc? If you have a Mustang you could get a pretty accurate review on your car but available judges just don't have broad enough knowledge to do anything else justice. I'm guessing it's a similar situation in most places.
