I 've never had 49er anything. Raiders? Everything one time or another. The last few years as I wore my Raider hat or sweatshirt...I had to watch in the blue collar eastbay cars with 49er decals,49 flags. I wrote about this last year. I stuck to Raiders.
Now? I dont see 49er flags right about now. Soon,those Raider decals covering the back window of the black SUV will return. I never left.
Same for the A's.
