I had an idea where the modern US is ISOTed to the old world, So I did a thing where I transposed 2000 municipalities from the lower 48 states onto positions in the Old World:

The map is searchable. Latitudes are exactly the same for all cities, but longitude is... funny. I tried to (1) preserve relative longitudes so that a city to the east would stay to the east and vice-versa, and (2) position cities so that they ended up in a place that's survivable and not in the middle of a desert or ocean. To that end I used a spreadsheet with the latitudes and longitudes of both old world cities and new world cities and did a bit of matching. However, my goals began to contradict each other and I ended up with some weird results, like some cities in Maryland being west of some cities in Iowa. Even so, the east coast is on the east coast and the west coast is on the west coast, and cities on water are not too far from land.
