It's about where you were born OR bred.
However, if I moved to somewhere out of reach of my roots, I would try to support the team there. I am, after all, a massive RL fan, as much as a fan of my club.
And, yes, I was being a bit tongue in cheek with this thread, but the point about nouveau fans from outside of Leeds, suddenly being Loiners is valid.
That's glory hunting and certainly looks that there will be no glory at Headingley this year. What will those fans do?
Oh, BTW, I think Leeds generate the best match day experience going and fully understand why they attract fans from outside their normal catchment.
