I am a bit of a contrarian in this. I would appreciate some improvement for convenience sake, but I don’t really mind the stuffed concourses. For me it adds a bit to the gameday experience and the vibe that it is a packed house and the place to be.
I grew up in the days when as a kid I would hitch a ride with my parents or a friend or whomever and buy a GA ticket at the gate. Then I would “somehow” make my way into the reserved seating and sit with my parents or my friend’s parents, with plenty of room. Or the days after the Rice remodel when you could easily cruise the underground concourses below field level. They felt like you had a sideline pass. But less of that “vibe.”
So yes, I don’t mind so much given my “back in my day” experiences. Good problems to have.
