Those are only three of the many old, central colleges though - Wadham, Keble, Balliol, the Turl St colleges, Hertford - plenty of history, a lack of tourists. And Magdalen has enough areas tourists can't go to keep undergrads sane (I spent a lot of time at Magdalen this term), and the postgrads are housed on the far side of Batwing Meadow, I think, which is the closest you will get to living in a country park in Oxford (even more so than LMH!). Being at LMH, the snotty kids from the Dragon School would get on my wick, they annoyed me in the course of one afternoon's punting past LMH!
