Repeater use will be tough if there will be a lot of comm traffic. Waltham would probably be the best one to use, but you'd need to get permission to take over the repeater for a couple hours. Waltham is kind of a busy repeater...so the odds are not in our favor.
I think, honestly, the best option would be to distribute hams throughout the train of vehicles and have them relay back and forth. A control operator would need to be in charge...possibly with the event organizer and then he can relay back/forth up and down the line. That way, simplex is less hassle and you don't have to tie up a repeater for an hour or two...plus...you can change frequencies if need be.
Oh...and I already heard on NPR that the press is aware of the rally. Of course, their only comment was, "The organizers are asking participants to NOT bring confederate flags."
Nothing about the main point of the rally. Fighting an uphill battle here.
