I note this. If we had a similar discussion in baseball, we would actually be talking about architecture. Here we are not. Football stadiums, particularly at the college level, are pretty much all the same. Rectangular concrete deals, surrounded, in the typical case of a rural based land grant college that make up most of Div I-A, by fields, slummy appartments, or non-descript college buildings. Very few places are really special outside the gates, and nobody has mentioned them, at least for that reason (Washington, Tennessee, Mississippi, etc).
Rather, we are talking about the people IN the stadiums on game day. This is why college football is, as Bill King says, "God's Sport". This is why it is so special. And why those of us that love it will fight to our dying day to defend it from those that are incapable of understanding it and want to RUIN it by trading a fall night in Baton Rouge for a semi-final night game in Jerry World.
