Rex, I think you are too sensitive on this booing issue in the all star game. I have heard real booing before, and what I heard Tuesday evening was pretty mild. It was so mild that it was almost good natured booing. Even the players booed (booees?) were laughing, because they could sense the slightly humorous vein in the light hearted booing of some traditional rivals.
I don't boo either; it's too much trouble, but it is a traditional way for some fans to express themselves.
