Iowa Hawkeyes Fans Display Their "Cards" (COOL)

Now this is what you call crowd participation.  I can't get over how perfect it worked out considering these people had never practiced this before and you have to worry about thousands of people holding and flipping their cards at the right time.  The patriotic angle was very cool as well.  I don't think you could pull this off in a pro stadium because half of the people would still be in line for beer or the bathroom. 

Shout out to Tommy G for sending me the link.  I finally gave you some credit bro!
