You might check if VCDL is doing anything at the fair. Maybe coordinate with them. I imagine many of your table-workers would be VCDLers.
The only other thing I mention is a subtle shift from supporting OC to supporting 2A. Its a broader scope.
Maybe even promote CC at the same time. Maybe have applications printed off from the state police website, combined with other materials into a CHP packet, ready to hand to people.
