Washington D.C. (including Baltimore) - Any special observance at the Pentagon on 9/11/11?

I'll be in D.C. for the 10th anniversary.....I've tried asking a question at the Pentagon web site (so far, no response)....does anyone know if there is a service or program planned? Do I need a ticket? Will the Pentagon Metro stop be open that day? Any help appreciated!! Thanks.

Thanks, Annandaler -- don't know why my Google search didn't turn up that page!

Thanks again!
