I go jogging around the lakes in Rother Valley Country Park every Sunday morning with a friend.
At 9.30 am the sky and lake were a beautiful deep blue and I vowed to return later.
By the time I had done the food shopping and had lunch the weather had clouded over and it was grey.
Nevertheless, I returned, and at least the water does match the feathers of this goose I photographed (a Grey Lag Goose, I think)
