"In Federal Buildings"...nothing. No weapons of any kind.
"At college football games", if there are metal detectors or check points, nothing. They will be confiscated and persons possibly detained or arrested if caught.
"In school locker rooms", less than lethal maybe.
Anywhere else, I would rather my daughter be "Judged by 12, than carried by six". My daughters have had handguns for years. Told them (as a minor) if they would ever get pulled over with it, have the officer call me and I will vouch we are meeting at a shooting range and you are on the way there. There are adults now, so no more worries about that.
