The traffic sucks getting out of a big event.
The parking is poor, dirt and rock. Watch out if you aren't steady on your feet. The problem is the congestion post-event. After a 40K event the whole crowd swamps the two small exits. There is little traffic flow or control in the parking lots after an event, so you have lots of cars cutting in and across you.
I sat for 80 minutes and moved 1/2 mile. So either leave early or wander for a hour because you won't be moving far.
In fact pay the VIP parking fee, if you must.
A big problem they have there is road to the stadium is sandwiched between the parking lots and stadium. This means to get in/out the stadium you are constantly looking out for crossing pedestrians and vehicles cutting across. But that road and two exits just can't cope with 20K vehicles.
The stadium itself is okay. Good sight lines, just a sad scoreboard in modern terms. I just dread going there for big events.
