I worked at Westside Christian when I was in Portland. It's not that bad. You're making much ado about nothing. While it is varsity, it is the equivalent of a mediocre JV game at any public high school. It's a gym. You work the game and you go home. Were you seriously considering not allowing the game to be played? I assume you haven't been to Vernonia yet?
I can't wait till you're at one of the high schools that doesn't have a shadow line painted through the mascot at midcourt....
