I had a go at the US states. Done that in a quiz before (can't remember where or when - some sort of pub quiz) except that, that time, we had to
place the states in the correct locations on an 'empty' US map, not just name them. More difficult!
So - perhaps I have an unfair advantage (despite not knowing my way around USA - only been there once for the briefest of visits).
Anyway. Got all 50. But with only about 2 minutes left.

Which one, then, was the one that gave me the most trouble - the one I spent about half my allotted ten minutes trying to think of...?
Arkansas. WTF?
