As the forum's resident Italian (unless there's another among us?) I'll jump on this tangent...
I grew up in Oxford, but my family's originally from Sardinia, so felt like I should have some connection to Cagliari, but I've never actually been to see a match there as I usually go over to visit in the summers, during the closed season. The rest of my Italian family live in Perugia, so I felt the slightest of loyalties towards them, but I went to study in Terni when I was 18, and lived round the corner from Ternana's stadium (Perugia's main rivals). All my mates there were season ticket holders in their main "curva" and after going to my first match with them, I fell in love and bought myself a season ticket too.
(Apologies for posting these particular colours on this forum)
