I like the idea of a big nice, "classy" sign (8'x6' or so) neon or ?,,maybe setup on the back of very nice truck parked in a great location by assembly halls/stadiums during district assemblies. Of course, someone would have to be there (to protect the sign), perhaps a city permit would have to be acquired. Standing there with just a little sign that not many could read wouldn't be my style.
What would good signs say:
