Yeah, I enjoy hearing people's "that's why I support XYZ" stories too. It's interesting to know what motivates people to follow a club that sometimes they have no local affiliation to.
My story is that although I am supposed to be a Villa supporter (my entire family are Villans and we are from Birmingham), my uncle (who used to play for Villa) was the assistant manager at Southampton and I went back to the UK with my mum when I was 11 years old and he took me on a tour of the club - a real "behind the scenes" thing.
I met legends of the club and the game (Alan Ball, Peter Shilton, Kevin Keegan, Nick Holmes, Steve Moran, etc etc) and instantly became a fan. Also got to "train" with them and put a sweet goal past Shilton (he swore he was really trying to save it), from a lovely through-ball from Kev. Memories...
So there you go - been a Saints fan since the very early 1980's.
