Best value guided tour of many my wife and I have done in various countries. Brian is extremely knowledgeable, and not just mundane facts. He is very well read, thus has all sorts of quirky/fun facts and interesting anecdotes about the power, politics and people of DC over the centuries, not to mention events your grandchildren will enjoy at different times of the year. In addition to the extensive and interesting content, the kick bike scooters allow you to cover a tremendous amount of ground in 5 hours (in a fun way!) including all the usual war memorials, presidential memorials, governmental and cultural buildings. We even made it to the Pentagon 9/11 memorial and the Air Force memorial, partly because there were just two of us and we could move fast. You can’t beat this tour for fun, breadth, history, politics and personalities.
