I saw there was a thread on this, but I would like to tell everyone I saw a real life skateboarding dog in Greenwich Park on Saturday.
It was amazing. My friend and I had just walked through the gate out of the flower garden bit, and there is an avenue of trees with a path in front. Nobody was around; all was silent. The a skateboarding dog sailed by, silently, with no owner.
It was one of the most beautiful moments of my life.
