I was surprised how few Cardinals fans were at the games in DC. There are usually quite a bit more during the regular season games. I have family near Champaign, Illinois and their town is pretty evenly split between Sox, Cubs and Cards fans.
i thought i saw that you guys were over 100% attendance for the series. I suspect that were just no tickets left. Also, i would be scared for my life traveling to another teams stadium during playoff time. Even when my team did score i would probably never stand up and cheer in order not to be singled out. Just wouldn't be worth spending money. But that could also be the paranoid side of me.
