Bunch of extra states with similar shapes to existing states, so it messes with your eye and kinda blends in.
Might be harder to do with a map of Africa, Asia, Europe or south America because there aren't as many straight line borders and things are a bit more curvy.
I see what you mean about this map being anomalous. Some of the states seem to be doubled, I wondered where they got that 64 states figure from!! My bad!
What's interesting are the states you can't modify too much or it gives away the game.
Texas is a key example, people are pretty familiar with that shape, even many non-Americans will recognize it. Florida and California are also pretty well known. Also, many people have a rough idea of NY State, though you could probably tweak the north and west borders a bit and nobody would notice too much.
The ones it's easy to fiddle with are the rectangular ones in the mid-west. I think a lot of people only know them starting from another reference point, like "north of Texas" or "east of Nevada".
Unless you're including all the minor islands and territories, the U.S. only has 50 states to speak of. I know I could identify my state, Texas, Hawaii, California and a couple others. If there are people who can name up to 50 states and where they are on a map, that's pretty damn impressive!
Calm down. Yes, of course there are a few people who can, but fortunately most of them live in that small part of the world that is still outside the US.
That's true. I doubt most U.S. citizens could actually name most of the states or their locations on a map of the U.S. All I'm saying is that if they can, that's pretty impressive - because so many young people today can't even name a country at random.
