I'm incredibly surprised that few (if any) of you have not heard of Snooker!

Here's a map of Durham. I've circled my college, and where I have my lectures. And this is the view from one of my windows.



From my college to the P in square E3 it's about a mile - Durham is a fantastically small city (well, the town itself and the University campus. If you take the housing estates outside of the city into account, then it's probably a few times bigger, with a much larger area). The big city campuses like London, or Manchester, can have distances of three or four miles between Halls of Residence and Lecture Rooms/Departments.
