When I lived in Maryland, there was a girl whose parents managed to make the school allow their daughter to play football over much objection. Not sur,e if they sued or just threatened to. She was seriously injured then they sued the school saying that they were not told that she could be injured.

It sounds like the parents had a terminal case of stupid. Women can't play the game the way the men do. As an example, (being as I am a hockey fan, first and foremost) in 2006, the US women's Olympic hockey team played the Warroad, Minn (population about 1,500) boys high school team, and lost.
