Looks like the question is "is the school board located on the property of a school?" If yes, then it a big ****ing NO-NO to carry in Colorado. If it's not on school property as in a Elementary, Middle or High School school, I don't think the HQ of a school district would apply unless it's also occupied by an active school.

If I where him, I wouldn't have said shit about it and just carried if the board room is not on school grounds. But if they want to state that the board room is part of a school, I don't think I would want any part of that legal fight. You might win in State Supreme Court, but I'd rather not get into the fight in the first place.
