Cape Cod Trip - Day 10

Up very early, despite no sleep... Over to DC (took US-50 into the city, probably a mistake...). Parked in town and had a chance to visit several Smithsonian Museums: Air & Space, Natural History and some pretty gardens. Gayle's highlight was getting to see the Hope Diamond. While she and Nicky were looking for it, the twins started crying a bunch - it echoed loudly in the museum entrance and everyone glared at me... Nicky gave me a couple of hours in the National Archives - it worked out great (found several important things). Weather was nice all day. Leaving town, drove to Arlington and showed Nicky and Gayle the cemetery stone where Mark was buried. It is still sad to think about how we lost him - just a year and a half ago... Gas at 1530 and then I-95 into North Carolina. Stopped for the night - late...
