I would attend my college's homecoming games, and I think the rule was, if the game was at your school, your team was the only one that had cheerleaders.
The Salve cheerleaders did a halftime dance routine, but every once in a while, they'd step in and do mini cheers.
An example:
Sit back, buckle in, the Seahawks will win.
at my high school, the away team can have cheerleaders too. at one of our biggest games (halloween) the away team only had about 10 cheerleaders! xD
