From Long Acre, 16th May 2010

You wouldn't know it from these sunny bookends, but in the short hour or so between this and the last there was a torrential spring downpour that left the streets slick and reflective and sent Sunday shoppers scurrying for cover. This cluster shot up to the west and my first shot was blinded by the sun, but it drifted with the weather eastwards above me and stayed low enough for a good view.

River Thames, from Waterloo Bridge, 16th May 2010

I spotted this one from a bus on a painfully slow journey north from visiting friends in the far-flung south-east of London, and having failed to snap it from the top deck, hopped off at the next stop in the hope it would still be there. The current wasn't strong and the wind wasn't either, so it was. I had the luxury of a few shots as it moved erratically eastwards near the northern shore, but the ducks and boat made this my favourite.

Wilton Road, 3rd May 2010

The first for what seemed like ages. The stalked pink was being hurried south by a biting northerly wind in the sun, and it hopped and twisted its way down the road past the indifferent buses and cabs. By the time my bus arrived it was still intact, rolling in a pedestrian corridor constructed as a safe passage by some roadworks.

Also, ironically, having decided not to include any more treed balloons due to their hardly fleeting nature, I honestly haven't seen one since the last.
