United States

8pm is early for the date you went. Sunset there is about ten to eight this week and there is still colour in the sky until twenty past, so your first half hour goes on that flat blue where nothing has an edge to it. I would push the whole start back forty five minutes. West facing glass above roughly the thirtieth floor goes orange for maybe ten minutes and that is the only thing all evening that changes while you are stood there looking at it.

I am going to disagree with Ben and I have never even been to New York, so weigh that how you like. I did a night walking thing in Rome that started at nine and by half eleven I was sat on a kerb near Campo de' Fiori looking at nothing at all. Two weeks of leave a year has taught me my limit is about three hours after dark. He is right about the light. I would still take the earlier slot and be in bed.
