He he, the Open Day tactics won you over then. It's not for everyone, but it's a good laugh.
Durham can be really cool and friendly for clubbing. Most clubs, especially the famous student-only Klute, have 'college nights'. For example if I'm out on a Monday night and decide to carry on to a club, I can go to Klute knowing it will be full of Cuthbert's students and so I'll know several people there, any week. You'll soon learn when Mary's Klute night is.
Then there are the bar crawls, run by colleges and societies, with various themes. When a group comes into the bar it's fun to guess what the theme is.
I'm currently in Canada(Vancouver) in a year abroad from Durham.
