The concept of a free country was born within a few square blocks. We will visit the revered structures of the past, including those where the Declaration of Independence and the Constitution were drafted, where presidents lived, and where delegates discussed the destiny of our nation. Along the route, we'll pass by a few well-known artifacts and discover the mysteries and tales these structures conceal. We'll talk about some names you've probably never heard of and share some historical obscurities. Let's hop in our time machine and head back to America in the 18th century.
