If you happen to be in Missoula, Montana on the day of the local university's home football game, you will see a sea of maroon floating towards campus.
My suggestion? Get yourself a t-shirt and a ticket, join one of the countless, bacchanalian tailgating parties, and make some noise.
The highlight of the season happens when the rival Montana State Bobcats roll into town. When the Griz and the Cats go claw to claw, the energy is explosive and festivities last all night.
