There's a thin line between enjoying yourself and having a good time. If you want to have a good time, I know of a thousand better ways to spend $700 for a good time. This is a contest, a competition, treat it as such. Besides, you "having fun" could be a nuisance to your neighbors.
I should add too, that BBQ people are the freindliest people in this country. If you have a question, ask. If you need help, ask.
