First, there are always tickets available from scalpers. I would suggest waiting until you get on campus if you want to go that route. You may want to first also check online with say stubhub, for tickets, depending on how much you want to pay. We will be going to the MSU game, and right now the cheapest ducat there is $130.00.
Last year, we bought tickets on campus 1 hour prior to the start of the Stanford game for $10.00 each!
Also, returned tickets often are available on game days at the Will Call Window at the Stadium Ticket Office. It opens 2 hours prior to kickoff, however a queue line starts forming early in the morning. I have never gone this route-too much waiting in line.
If you cannot get tickets through these routes, fans without tickets can watch the game on television at a variety of locations on campus. Telecasts of the games are available free at the Joyce Center, LaFortune Student Center and the Morris Inn, and food and beverage concessions are available at most of these locations.
Personally I like the atmosphere at the Morris Inn. The TV’s are set up in tents behind the Inn, and you can hear the roars from the stadium when ND makes a great play.
I have been to many games at both Ohio State (obviously) and Penn State, and I must say that you are correct; no one tailgates like ND Fans!
