With a slightly better understanding of the focusing capability on my camera, I was able to achieve the above shot. It was a best of twenty which is a significant improvement especially considering the motion of the horse - both the obvious rotation and the not-so-obvious up-and-down movement.
Our day started with a tube journey into Central London, followed by a walk by the Thames. Then we watched street performers near the Shell building (one named Richard was particularly good), and went on to see London through her Eye. For lunch, we took the bus to Wigmore Street's Wagamama (it's bigger than the Picadilly one) - and had ice cream (99) just prior to taking the tube home.
The day was very much like this mary go round. Nothing particularly new, nothing original, but loads of fun.
