One Degree Of Separation

How can you get from the Cardinals' outfield to the international border between the United States and Canada in two people?

Start with Cardinals' outfielder Jon Jay, one of those rare players who has two first names, each the same length, and both of which start with the same letter. 

John Jay was the first Chief Justice of the United States Supreme Court, serving from 1789 to 1795. 

While Chief Justice, he negotiated Jay's Treaty with Great Britain which, among other things, defined the border between British North America and the Northwest Territory. 

After the Revolutionary War, British forces continued to occupy six forts in the land lost to the new American nation, including Fort Detroit. Per the treaty, they retreated to their side of the water boundary that now separates Michigan from Ontario, and Port Huron from Sarnia. 

So, when the Cardinals play, and Jon Jay comes up, you get to think about American history. And that's how you learn history.
