I do agree in that the Spurs do have some very classy fans. But at the same time, I guess you're forced to be loyal to the only game in town. If I lived in San Antonio, then I'd bleed Spurs blood as well.
I don't live in San Antonio, heck, I'm nowhere near Texas for that matter. I'm a Spurs fans from SouthEast Asia.

I have 2 brothers; one of them was a Suns fan and the other was a Mavs fan. They've both given up on their teams.
