The longest day

As I write, the sun is setting on the longest day of 2009. I should be outside watching it, but I've just come back from a long and unpleasant train journey between Penzance and London.

The attached photo is from two days ago at the south-western tip of England, the Isles of Scilly. This will be the last place to get dark this evening - but it's too late to get there now, sorry.
