The Walm writes in from London to alert us of a new service called WalkIt. The service maps your walk through the streets of London. This is important for two reasons, 1) London has some of the most confusing streets in the world and I found myself lost quite often, and 2) The Walm likes to call London the "most unhealthy city in the world" and I think he might be right. Anything that can get people walking more there is a good thing.
I mapped my favorite walk, from Regent's Park, which I used to live, to Burroughs Market, the site of a wonderful gourmet food market with the best burgers and coffee I've ever had. Mmm...burgers and coffee.
