Ok, I was a bit hasty in my report about the two girls that fell into the mine shaft. Their father was with them, but he was riding ahead of them on a dirt bike so didn't see them fall into the hole. The search took twelve hours, but people were looking for them all night. And apparantly that area of the country is riddled with old abandoned mine shafts. I still think that he should have been behind the girls so he could keep an eye on them, but then again it's really impossible to judge the situation from this chair. It's a terrible tragedy, but it sounds like it is yet another accident that probably couldn't have been prevented.
