Cannon Falls Area Schools announce that the Cannon Falls Emergency Responders will present a mock crash for students in the 9th through 12th grade on Thursday, May 4th. The simulation will include participants from the CFPD, the CFFD, the GCSO, and the Stat Patrol. As part of the simulation, an emergency response helicopter will respond, as if in a real-time event. The simulation will interrupt traffic access to the school until about 10 AM. School administration asks that visitors and parents avoid coming to campus during this time.
