I did a test to see how many US states I could name (just name, not place though I did know the majority of those) and this is the result. I did an extensive trip through the west coast which is why I probably am more acquainted with those states.
HEY BRUSSELS! (I just thought I'd give that term a shout-out), the states you didn't get are pretty much just in The South. Nobody goes there and nobody really takes those states seriously anyway. For the most part, The Confederate States are still fighting The War all these years even after Lee's surrender.
