Went to the Library of Congress (thanks for the suggestion). Wow! That was amazing. Sooo much fun. They also have a temporary exhibit on the "Crystal Skull." Did I mention wow? They still use vacuum tubes to send book requests up to the deck where a librarian finds the book and sends it down a dumbwaiter. They have 5,000 employees plus 1,400 librarians. And a great little bistro nearby.
