from my experience it is far worse outside the stadium
the revelry is completely out of control. Honestly, it is really bad. Go hangout by the tailgate lot before, during or after a game in BYU gear, watch what happens. Constant taunting, yelling, obscenities about women, garments, every vile t hing you can imagine. Even the utah faithful who are LDS avoid those places. It is similar to what Obiwan Kenobi called the cantina in Mos Eisley:
This is the tailgate lot by rice eccles. Go and see for yourself. As game time draws near, trailer parks in west valley and ogden empty and the tailgate lot fills up. These same folks are at Lagoon on opening day.
