Set out yesterday lunchtime with the intent of finishing off the London Borough of Camden. Instead, I got lost somewhere north of Hampstead Heath, so I only got the Camden/Haringey border finished, and not the borders with Barnet , Brent and Westminster. I think I'll attack the border from the other direction for my next attempt : I know that the A5 Edgware Road is the western border, so I can start from there.
