Well, see if this makes your decision any easier. I will be premiering my film, “Rockin’ the Wall,” how rock ripped the Iron Curtain, on 9/9 at the 9/12 March, and will speak at the 9/11 Mall gathering.
Wow, wish we could be there, but I think it's impossible at this late date.
With FR and other sites, I'm pretty clued into events like this. I'm not sure why I'm just learning about the September 9-12 events in DC just now. So there are gatherings on the Mall for 3 days in a row? I'm still confused, apparently.
Most likely, we'll just have to "be there in spirit". :-(
