There are a few pink Horse Chestnut trees by St. Alfege's Church in Greenwich, which are covering the churchyard in their pretty pink blossom at the moment. I was about to take a photo of it the other night, but noticed a rough-looking man sitting on the bench by the tree behind, looking at me with a wild look in his eyes, swigging on a bottle...so I trotted off, sharpish and photo-less!
