This is Kenilworth Racecourse, the oldest racecourse in the country and home to the annual J&B Met - a high-fashion affair, with plenty of large hats, designer suits, and very, very short skirts. Oh, apparently there's a little bit of horse-racing too, but you'd never guess so based on the TV coverage of the event.
The J&B Met has been on my to-do list for a really long time, and maybe with a bit of planning we'll actually make it there in 2008 (I don't mind wearing a hat, but my skirt will be of a modest length).
