First off, don't be discouraged by the dick sitting next to you. He's at every class sometimes he's a cook from an almost star BBQ team, sometimes he knows someone who knows everything about BBQ, sometimes he is an expert at the 'ol gas grill.
Mostly listen to the intent of what KCBS is wanting from you. These are the rules, read them more than just the one time. Here is how we want you to do this, so that all teams are starting out on even playing feilds.
Your taste and preference does matter, but it shall be apllied in a fair and even manor.
I think the only way to understand everyone's thoughts and intentions is to stand in their shoes for a while.
In the end, you'll get from the class exactly what you put into the class.
Have fun, learn some, and grow each time you judge. I've come to the conclusion after 4 years, you'lll never know it all.
