Just a newspaperman's proofreader habit of mine. No biggie, I think it's generally clear, but you might fix it in any updates or additional posts between now and then, especially if you cut-and-paste from this one.
Good luck with the rally. I may get to D.C. for the Rolling Thunder/Run For The Wall annual bikie/veteran's Memorial Day run, but eventhat's going to be on a borrowed bike if I can make it, so I doubt I can get there for your shindig on this short a notice. But I'll pass the word on to some pals a little closer than I am [Memphis] and to a few news folks in the DC area. They're generally sympathetic, but their bosses aren't.
