Did you know that about a third of University students don't drink at all ....?
All Student Unions are very conscious of this - and that having everything revolving around getting wasted doesn't do much to dispel the reputation for laddish behaviour or the overall image of the Uni.
So ALL Unis will have a load of stuff that doesnt involve drinking - cinema trips, coffee crawls, daytime/evening sightseeing walks, quiz nights, trips to the zoo, you name it. And of course, you can go to the pub without drinking alcohol - no-one will actually think this in any way odd.
