I was fresh off my mission and got a job working grounds at Cougar Stadium, and part of the job was to help clean up during & after games. So I got assigned to walk around the West stands with a broom & dustpan sweeping up garbage, but mostly I just stayed on the lower walkway (just behind the lowest section of seats) watching the game and following the ball up and down the field so that I could watch every play from the line-of-scrimmage.
I didn't grow up in Utah and hadn't paid any attention to BYU sports as a kid, but after a couple of games, I was a fan for life.
