Things have improved a bit as there is now a trailer at the back of the grandstand where the marshals association sign people up.
Things could still be a whole lot better on the advertising front and I am going to write some suggestions up and put them to the powers that be.
As for ferry reductions, it would be nice but I won't hold my breath. Anyway it would be very difficult to stop people abusing it. Say you're going to marshal, get your discount, then don't bother. But then I'm an old cynic.
