This subject has been beaten to death. It is whining and complaining that give enthusiasts a bad name. I am not condoning the GP booing, I thought it was bad form. However, what if the GP got in the way of your ERT? I am sure there would be flames on all the boards about the rude and inconsiderate GP. Enthusiast's season pass revenues certainly couldn't pay for MF or Goliath, or even a simple corkscrew or boomerang.
As for more knowledgable riders, give us a break. The people who have the time to study track design elements, manufacturer specs, etc. have time on their hands. They are either students or unemployed. Once you grow up, get careers (not just a job at the local mall food court), you'll understand more clearly. It's nice to see real people for a change. Enjoy the fact that you can get so excited about roller coasters, while you can.
