Tidbit: Determining How The World Ships

Vesselfinder, https://www.vesselfinder.com/, is not the only ship tracking site out there. I reached out to someone in shipping and they use another site and so it goes. Still, the idea of watching ships at sea, or navigating the great lakes, or rivers, provides a sense of where cargo goes and how the material in the world actually travels. This should be required for everyone to know.
