I have been to Washington, DC 4 times. Most times, having done all the government buildings and Smithsonian Museums. On my most recent trip a month ago, I went to the Newseum! Wow is this museum amazing and relevant to our times... although one could argue it is relevant to all times! The website indicated its about a 3 hour visit. You start on the basement floor with a couple introductory films, the Berlin Wall and an FBI exhibit. It took me almost 2 hours to get through this floor and I didn't read everything. I could have spent the whole day pouring over this entire museum. Don't miss the amazing views of the Capitol from the 6th floor terrace.
