How long is the rugby season in England?
Maybe this has been mentioned before, but if the Houston Stadium is built with gridiron in mind thye will have to have the sideline seating high up like most American parks to get the front row views over the heads of the mass of players, coaches, camera crews, officials, etc that litter football sidelines. This eliminates the British style seating atmosphere but in the long run the views are much better with that extra height, IMHO.
