Exploring the OLDEST FORT in the USA

Our home state of Missouri has some history to be sure, but nothing like the history on the East Coast of the USA (much less the history of Europe). So, it's always a thrill for us to check out historic towns and structures. In this one, we visit the oldest city in the USA - Saint Augustine - and explore the oldest fort in the USA, the fabulous Castillo de San Marcos. Oh, and it blew our mind that we could anchor the boat so close to such an impressive building!
