People may have noticed a lot of emergency vehicles and a MedStar helicopter at Central Valley High School yesterday morning. Nothing went wrong; the school was just hosting a mock crash demonstration. They are held every couple of years to warn students of the possible consequences of drinking and driving. Students play the role of victims and some schools have even been known to put on fake funerals to go with it. I've been to one before and they can be incredibly realistic. You can check tomorrow's Valley Voice for a few more details on how it went in the weekly fire department roundup. All photos are courtesy of the Spokane Valley Fire Department.
