Here's a
first cut at a route in Bikely.com. It goes from Union Station to the Capitol, down the Mall, over to Arlington and the Iwo Jima memorial, down to Hains Point and the Awakening, back up around the White House, and back to Union Station. Changes/suggestions are welcome. There will of course be lots of stops at monuments along the way for photo ops and such.
I agree that we should do this as early as is reasonable, and end up somewhere for lunch. Maybe Tam can join us for lunch?
