I managed to knock off a reasonable chunk of the roads I had left to walk around the University at the north-eastern extremity of my mile on this nice sunny walk. As well as being impressed by the number of big townhouses now occupied by various departments, I took some time on my way there to check out a war memorial, and some time on the way back to do a little extra wandering of Berkeley Square.
Seems appropriate with the amount of time I spend staring at maps at the moment. I imagine there's a cartography sub-department...
