Eleven man, with that small of schools? My son was on a 6 man team, and there the ruling that if one team is ahead by 50 points at half-time the game is called a win for one side and other side crawls off. We left two games (mercifully) early because of that and one of them was a Homecoming game.:)
We had a game last year where we played the second half with a running clock, because we were so far ahead, but we haven't actually stopped a game for anything but lightning. Most of the six man schools only have about 150 or so people in the whole town. One of the things I love about small town high school football is that the kids really are students first. One of the Crawford kids has been accepted to the Citadel, and another is going to Texas A&M. Both of these kids got in on grades, not athletics. By the way, at the risk of hopelessly bragging, around 70% of the Crawford kids go to college and get four year degrees, including the athletes.
