You probably aren’t American, but can you name all fifty states in ten minutes? I got 48. It would have been 49 if I could remember how to spell ‘Massachusetts.’ With that freebie, why not see how good you are at it.
PS. Which one did I forget entirely? One hint: while there are a few sets of North-South states, there is only one ‘West’ state.
PPS. One more hint: start with the ones you have visited. Then, do the coasts. Then, think of the states major cities are in. Then, think about recent news events, prominent primary elections, and whatever else can possibly assist you in the last couple of minutes.
