The Hood River County School District is preparing for forecasted winter weather Wednesday morning.  Superintendent Rich Polkinghorn outlines the factors involved in determining whether to simply delay school or cancel outright, which mainly is whether the roads are clear enough to run the buses and what the weather is projected to do through the day.  Polkinghorn noted the district’s buses are built for rugged weather, and chains can be placed on all of them.  Some of them have drop down chains built in.
