99% Invisible mentions Peace Arch Park, which is along the US-Canada border in Blaine, Washington, and Surrey, British Columbia. Anyone from either country can enter the park and mingle with people from the other country. There's supposedly strong incentive, because of a treaty from the War of 1812, for both countries to keep their side of the park open:
If Canada broke the treaty, in theory, the U.S. could lay claim to parts of Ontario and Quebec. And if America broke it, Canada could get parts of Maine, Michigan, and Wisconsin. So, basically, North American geography as we know it is contingent on this early 1800s treaty remaining in effect.
The podcast was from December -- an eternity ago in these interesting times -- and I don't know whether anything has changed since then.
