I'm curious as to what level would we consider a conflict of interest. I got to thinking about that today when I read an article on a local newspaper's website.

But what if it wasn't so obvious like if your kid was in the band or a cheerleader. Or, if it was your alma mater in a town where you no longer live and it's been 15 years since you went to the school. I guess the real answer is "it depends" and there are no real rules per-se.
The umpire in the article is probably very fair and I don't know him so I can't and won't comment on his integrity. The only 2nd-guessing I would do is to not put myself in a situation where I could be judged to be biased.
But again, what if it were indirect? Cheerleader, Band, Pep-Squad, alma mater of 20 years and you no longer live there, etc. etc.
I'm sure the real answer is just using common sense to each unqiue situation.
