We then walked down to the Nation Archives which have been closed since the flooding here in DC. It finally opened the day we were leaving so we ran in and looked at the Constitution and the Declaration of Independence.
We then went back and checked out of the hotel. We caught a circulator bus back to Union Station and checked our baggage at the Amtrak counter. We grabbed some lunch in Union Station and ran next door the the Postal Museum.
Now we are back at Union Station in the Acela Lounge (lounge for sleeper car passengers). We have about two hours until departure. Looking forward to getting back on the train!
Perhaps be able to post some more tomorrow in Chicago.
