Indeed, AD was Chris Miller's house. It's a bit of a different house these days than the one portrayed in the movie. Mostly it's well off rugby players and Ambercrombie zombies. At least is was in '89-'93. These things change. They were in a bit of a bind then over some ill-advised sink-night audio tapes (when pledges 'sink' their bids' - think 'Thank you sir, may I have another!'/KevinBacon) with some less than PC discussion of women.

SigEp's (or at least was) mostly track guys & good students.
