Recently, Dan W went for a rather wild walk:
The other week I crossed the international border from the Netherlands into the Belgian village of Baarle-Hertog. I continued walking in a straight line. A few minutes later I walked out of the other side of Baarle-Hertog, back into the Dutch village of Baarle-Nassau.
Inside of the Netherlands lie a few small portions of Belgium. Inside those small portions of Belgium are several even smaller portions of the Netherlands. It’s more than a bit odd.
