If we had stayed in the north I'm sure I would not be ready to go home today. But to me a city feels like too much stuff packed into such a small space but somehow separated by a lot of travel. London's density works against you. I'm sure there is some sort of law of physics involved. I mapped a location in London the other day and the tube was going to take us the same amount of time it would to walk. We needed some space.
We rented a car and drove out to Avebury. Its was an amazingly gorgeous day until the heaven's opened up and poured but we were tucking in at the pub by then.
