I never got to go to old Mile High but I grew up watching Elway there on tv. Tv screen bouncing and all because of the noise. Why is this stadium so much more quiet? Mile High was a loud mofo and it wasnt just the altitude that made teams hate going there.
Part of the reason Invesco isn't as loud is the fans. When the new stadium opened, ownership took it as an opportunity to move long-standing season ticket holders out of their awesome seats and sell the close-in ones to people who could afford to pay more. Beyond stadium design issues, we now have the wine and cheese crowd in the lower tier.
