Don't miss the free tour of the Library of Congress while in Washington DC. I put it on our Washington itinerary as Kalyra is a big book lover, but I think I enjoyed it more. I was in awe over the interior design and loved seeing Thomas Jefferson's book collection and the Reading Room Book in advance! Full guide on yTravelBlog.com as well as one on exploring the National Mall and itinerary guides. Link in bio. #familytravelblogger #exploringfamilies #happytravels #familytravels #libraryofcongres
