I remember the San Francisco Branch's shift from being a place where
people booked ahead, to the opposite. It was a process of educating the
dancers to understand it's more fun if you don't book ahead. I remember my
teachers encouraging us to say, "No thanks, I don't book ahead, but I'd
love to dance with you!" It was a gradual change. I don't know what the
situation is there now; but it took more than removing the sign-up list
from the program booklets to make it happen.
