Locdog - I was in a similar situation a few weeks back and did have someone become injured, although probably a minor ankle twist.
Another Small Gym Story
I also asked for opinions on the Forum.
BOTTOM LINE: Gym was there before your game and it will be there when you're gone. Hundreds of officials and players have been there before and will be there again.
Does that make it any better? No.
I reported it to my Association, have a clear conscience, and am done with it. Let the school, administrators, parents, etc. worry about it. If it's safe enough for them every day, who am I to say otherwise?
But, I still don't like it.
GIGDGO and if I never go back there, it'll be fine too.
Off soapbox.
