This week's challenge could also prove quite easy. It's hard to pick islands that are not instantly-recognisable, but also not completely obscure. The range is on the instantly-recognisable end of the scale :)
UPDATE: Trivia: There's at least two states and three countries in this collection :)

I've no idea what any of them are -- which is sad as I've been to Manhattan several times (though never suspended above it at satellite height).
As I desperatley want to play the game, I've decided to modify the rules and turn this into which two islands do I like best based on appearance: The answer is 2 and 9. (My apologies ... but, as you know I'm an American and we refuse to play by anybody's rules other than our own.)

Well 2 I am going to in October and 9 is high on my want to go to list (but is also very unlikely to be guessed :) .. Gary may get it if he still reads this blog, he recently posted a video on his blog that was filmed there)
