Thanks to Lucy Rawe, who's just pointed out this excellent little site which allows you to calculate the "walkability" of your neighbourhood.
The idea is that walkable neighbourhoods are healthier, more environmentally friendly, more sociable, and have stronger local businesses... So, if you type in your address, WalkScore will plot the amenities local to you in a Google Map, and give you a score out of 100 for the walkability of your neighbourhood... Unfortunately, my neighbourhood is not very walkable at all; my score was an abysmal 7 out of 100 (although the shop next but one, and the pub four doors away are not listed). School scores slightly higher - 27 out of 100.
