Anyone interested in American history should watch Ken Burns Baseball. It’s an excellent documentary series about baseball that’s packed full of fun facts like this. One of my favorite facts I learned was that people sang the Star Spangled Banner at baseball games before it was established as our national anthem. The documentary goes through the history of baseball and how everything that has happened to the sport beautifully depicts everything that has happened in the country’s history through the lens of baseball. For all the good and bad, it’s a great documentary series. 10/10 highly recommend!
