I've walked around the St. Paul's area, though not the cathedral itself. Some nice little parks, churches and remains of churches, part of the Roman wall, and visited the Museum of London. Then went to South Kensington to the Science Museum to see if my article on that needed updating, but I think not much new. Then met a friend and went to the British Art Fair since I'd managed to get a free entry for 2 including a glass of wine each. Nice.

Beautiful sunny day and I felt full of energy. But I don't think I could do it again tomorrow. Whew!
