Serious Ivy League fans dress for the weather. As compared to the Yale Bowl, or Harvard's Soldier's Field, or Dartmouth's Memorial Field, the new Princeton stadium is fluff. It entirely lacks gravitas, authority. I suspect that unconsciously, or perhaps consciously, it was intended to denigrate serious football. But football is not entertainment.
Football is a collision sport.
Let Dartmouth people not be too much in awe of this strange architectural and cultural event. It is very much a thing of its moment, and not a very good moment at that. It may prolong that moment forever. You don't need postmodern fluff and jokeyness when the teams are playing real football. I doubt that the new Princeton stadium will send the right message to anyone who wants to.
