The answer gets pretty obvious. None in your class, if you don’t sign up.
There are several 4 cycle classes. We haven’t had an overwhelming turn out in the past. That said, 2 years ago, we had a guy pester us incessantly about his class, then cancel his pre-entry, stay home, and then find out later that it was the biggest class of the weekend. The sure fire way to kill your favorite class is to not enter, and see that your buds didn’t enter either, because you didn’t. Kind of a contageous situation. It feeds on itself and pretty soon your class disappears.
