No idea where the BYU section is or if there even is one. Ticket office was zero help. Just referred me to a link to ticketmaster. I bought mine direct from MSG ticket site. Tickets were $50 with a ton of fees on top of that. All lower level seats are $50 for this event. Very surprised that BYU or Cougar Club isn't chartering a plane and selling seats. It's not easy making last-minute plans and I'm guessing they could at least get a 150 people to buy a seat to cover the cost.
In spite of their lack of organization, I'm very much looking forward to watching the cougars in the garden next week. Win or lose it will be fun, but a couple more wins will make it a trip to remember.
