Back in 2002, Lucy and I went white water rafting in North Wales, and it was great fun, and something I in particular had wanted to do again. So today we paid a visit to the Lee Valley White Water Rafting Centre, built as part of the London 2012 Olympics facilities, on land that I used to visit on foot or bike when we lived in north London. It’s a shame in a way to see the green fringes being nibbled away with development, but what has been built is really excellent.
