Some of the things we can learn from maps
This map envisions what the U.S. would look like if our founders had drawn state borders to accommodate watersheds, not political boundaries. (Click image for larger-scale view.)
This is a reddit group that shares maps and what they can teach. Fair warning, it is the ultimate rabbit hole. You can never look at just one. Today for example, I learned that the very skinny but very long country of Chile would accommodate Switzerland, Belgium, Wales, Portugal, Austria, Denmark, and Italy within its borders, with room to spare. But of course I couldn't stop there. Not when a nearby post showed me that Brazil's northernmost point is closer to every country in the Americas than to Brazil's southernmost point. I've been to Chile. I've been to Brazil. I didn't know either of these geographic realities. You've been warned.
