Lady Margaret Hall quad in October. The weather was beautiful when I arrived! Oxford colleges have a no-walk policy regarding the bits of well-groomed grass on the front quads. Only Finalists and Professors can (at certain specified times) stroll on the verdure. This ignorant American made the mistake of walking over it within an hour of arriving. Twice. Result was getting shouted at by some third years and the Porter (who had a megaphone)!
