I'm not sure but give the current economic climate, I doubt anything is getting built in the near future.
How come places like Soldier field, Lambeau, and Heinz Field are considered iconic stadiums while the Ralph/New Era stadium is not? What makes those stadiums so prestigious? Is it the history? It would be nice if the Bills could cultivate a home venue like that instead of going with a dome. That's just my mindset, I guess you can call me old fashioned.
