How about if this be planned around a rally ? I would be darn difficult to do by Independence Day, but a huge rally, with as many of us as we can muster, lots of inspirational speakers, politicians. We should try to find allies in famous or well-known people whose friends or relatives have PD. Maybe the PD organizations could get involved, or the organizers of those PD walks could offer some advice on this. I think indoors would be better. There probably aren't enough of us to look meaningful outdoors.
