I saw very few Cardinals fans at the Park the last two games. As in almost none. It could be because they also wear read. Or it could be because they got a serious beat down. I'm sure getting beat like this by the lowly Washington Nationals is severely their world view.
I went to one of their message boards after game 2 and it was dire. They were so angry at all of their players and wanted to blow the entire team up (which is funny because before the series started, they assumed they were going to roll over us). I can't imagine it's any better today.
