First off we definitely need to build this
Second we need covered seating!
Third I like the idea of the parish tailgating area, but it doesn't have to be fancy, I think if they just opened it up to the public, and sold drinks and food it probably make more money that way then charging people 70 bucks, maybe we could charge like 10 bucks. Only on the NEZ and top of the visitor side keep the stands there!
Fourth- I really don't think fans that are buying premium seating care about being inside for the game, but as far as sitting in a nice chair back with a waiter or waitress to bring you food and drinks is the way to go
I will say keep it cheap and casual and you will make people more comfortable, and affordable! We don't need nothing to high end .
