When we caught the metro train at about 10:45pm last night at King Street, it was full of what the boys now call 'green people'. Comparing notes with other groups, it seemed that they had all had a great day. Some had visited Arlington National Cemetery; most had done the memorials including one group coming back from touring the Jefferson Memorial at night (it's lit up and very impressive); one group had visited the International Spy Museum which they said was great, and at least one group had dined at the Hard Rock Café. Seems like everyone is having a good experience. Today we plan to start with the new American Indian Museum and improvise from there. Clear and sunny so far this morning.
