Or, looked at another way, with the gentle slope of the Rose Bowl stadium, there are no good seats. And your track analogy? What is that about???? Very few colledge stadia have a track around the field anymore. Maybe Duke, Kansas .can’t think of any others ..
I don’t think the rose bowl is gently sloped.
Because half the stadium is below ground level, they could do a lot of things to get the upper level fans close without expensive support structures or using an upper deck.
The lack of luxury boxes also keeps things compact.
