Back in our '96 road trip, we returned to Ottawa to stay with a brother for the last couple of weeks before flying home. We drove to Quebec, then took a road north and kept going for what seemed a long while. Money had run out and credit cards were catching up with us, so there was little else we could do. Hours in, very remote, Newfoundland visible (I think), but we turned back, partly because we had run out of money and partly because the flat earthers might have been right and we'd drive right off the edge. It felt like that, anyway.
