My son is a A's fan, I like them both. On our nearly annual trips to the bay area (we have relatives and friends there) we catch some games. We've seen several A's / Giants games, almost all in Oakland since it's easier to get a ticket. I love the good natured ribbing that goes on in the stands
One of the games we were at in S.F. Eric Byrnes hit for the cycle, the only time I've ever seen that.
I remembered one time coming out of the Coliseum and some of the fans were saying the thing they could both agree on is "beat LA".
It's too bad we didn't get "Battle of the Bay II" this year, it really would have been fun
