I thought this would be a nightmare when I saw it was all presidents but the connections were very reasonable.

No use for anyone in UK - recognised presidents, but no more. Too specific to US, but thanks for the effort.

Sorry Sally. I agree that it is tricky but thought that one group could only be 4 presidents, cutting down the options for the other groups. The perils of trying a themed grid!

You are allowed to know things from outside your own country Sally.

Really taxing but definitely learnt something.

Really good -- though the banknotes one is super-obscure.

I don't usually like themed grids, but I enjoyed this one because the links weren't far-fetched. For example, every American trivia buff knows which four Presidents are on Mount Rushmore. I realize this grid would be difficult for someone outside the United States, but Americans should know these sets. (However, I connected the banknotes set under an alternative link: those Presidents each served for exactly two full terms.)

Too US focused.

Would have been nice to have had some Japanese Prime Ministers included.

Well thought out; bit scary at first but after the Mount Rushmore one it got a bit easier. And I don't think we Brits should protest at the American slant, part of the fun.
