A Foggy Day in London

London was famed at one time for its epic fog - a particularly noxious mix of climate and pollution. I remember in my childhood a conductor having to walk in front of a bus they were that thick.

These days they aren't as thick or frequent, but they occasionally lend an unearthly air such as here, in Hyde Park on my commute. Just for added weather interest, on Thursday it was 3 degrees when I left home, and 17 coming back in the evening.
