Sorry. I just edited my post to say Oct 24-Nov 4, because I had originally written that they shut it down yesterday (October 7)...at any rate, some of the buzz is that it's to keep people from spying on the Nemo work, but since they just started pretty recently I can't imagine they'd be doing anything all that significant during those days. Potentially it's for work on the Millionaire building in DCA, which is close to the Monorail. At any rate, bummer for those of us that will be there during the temporary closure.
