Earlier this week I found myself in London with two hours to kill, so instead of visiting one of the photo exhibitions on my list (as I'd been invited to one later that evening), I had a slow walk through Hyde Park.  It had been another day of 30 degree heat, and the condition of some of the trees showed how little rain there had been this summer.  The very next day the temperature dropped to 14 and torrential downpours caused flash flooding throughout the city.  Much more like the Septembers that the trees are used to.
