This is a must for anyone truly interested in the history of the White House, and the Presidency. Paul has a wealth of knowledge that he very much enjoys sharing. He encourages questions as you go along and isn't stuck on any particlur script or sequence. Besides learning a great deal, I was very much entertained by the stories and opinions Paul offers. If you have the privalige of taking this tour, I highly recommend it. Highlight of my trip, thanks Paul!
