And I am walking in london

Walkit.com's managed to improve its already excellent service by adding an option to search for routes that avoid busy, high-polution, roads, thus making your walk easier on the lungs, often at only a few minutes' cost. (I have also, while playing about testing that out, realised that one of my regular routes is about a mile longer than it needs to be - you live and learn.)

Unrelated thing: I have Samuel Pepys' Diary RSSd (it's a little overwhelming as a giant volume). Today's entry, with its reference to Pancake Day pleases me.
