TEMPE, AZ - Seventy thousand fans are expected to fill Sun Devil Stadium for Thursday night's big game against Oregon.
Fans are encouraged to wear black to "blackout the Ducks" and end ASU's seven-year losing streak against the long-time rival.
Perhaps the loudest section will be the students.
In order to get the best seats, dozens of them camped out on campus for 24 hours to get party passes to the game.
While they were waiting, a group hiked up "A" Mountain in the middle of the night and painted the "A" black for the blackout.
When the sun rose, the "A" wasn't black like they expected, but green!
Students blame the sneak attack on Oregon fans.
They quickly repainted it black and said the Ducks will pay on the field Thursday night.
