There's been over 60,000 at all 3 other semi finals (granted Dublin were in the hurling but Cork had the bigger support) in football in hurling so wouldn't necessarily say the gaa are relying on the Dubs for crowds. Even in the quarter finals there was 60,000 on the day not involving the Dubs. Though it is great to see a full house tomorrow and it should be a wonderful occassion. Hopefully the game lives up to it.
