If you don't, why not? Family ties? Glory hunting?
I can't imagine not supporting my local team. I love the fact that I can roll out of bed, stumble 20 minutes up the road and I'm in my seat. I even fear the day when I move away from Glasgow, as it'll mean no more football on a Saturday. It's probably the reason why I'll end up a sad, bitter loser who never moves away, purely because I want to see my eternally pish football team get shagged every Saturday.
