I go because I'd hate to not go on the day we smash someone 10-0, or score 2 in second half injury time to win.
Also, to see mates that I would otherwise never had met. And because, in a strange way, I feel very much at-home at St. Marys, almost like I can get away with anything because it's mine.
Similar reasons for getting aseason ticket, you never know when we might be in a final, win a league, get p*mpey in the FA Cup or some-such.
