1. MAJOR improvements in the concourses below each set of stands - new restrooms, concessions, etc. Time to step up to at least the mid-1980's in that department.
2. Build permanent seating (not many - like 1,000 - 1,500) in under the new jumbo tron thing, charge a cheap price and make it like a rowdy "Dawg Pound" type seating like the Cleveland Browns used to have. Would close in that end zone.
3. Come up with a design scheme for the exterior of the stadium using dark red/maroon brick work to make it fit in with the rest of the older campus buildings.
4. At least draw up some plans to close in the North End Zone with permanent seating.
5. Upgrade some seating on the West Side to Club Seating (I've heard on here that's already being discussed).
6. And this one is a reach, but it was done at both U. of Houston and Navy - and not as hard as it sounds (in fact both schools did it because it was the easiest way to add more prime sideline seating)... Lower the playing field about 8-10 feet and build more seating on the East and West sides that comes down closer to the sidelines. There used to be a track around Scott Field and that forced the stands to be pretty far away. Houston removed their track, dug their field out and dropped it 8 feet and then built more sideline stands in front of the existing stands. Navy did a similar thing. I think it would improve the home-field advantage to have fans closer to the field on both sides.
7. Install more aisles - some of the sections are a country mile long and if you are seated in the middle of those sections, you have to step over 500 people every time you need to hit the bathroom.
