Threats against Niwot High School have forced school administrators to cancel classes today.  The Boulder County Sheriff recommended closure because of two threats against students this week. A threat that the school was "going to blow on the 11th" was scrawled on a bathroom stall Monday.  Then Thursday's threat was a 'hit list' that contained names of 30 students . The Longmont Times Call  says many on the list were athletes. At this point, the school is scheduled to reopen Monday.
