In short – winter weather. We use the same dump trucks for snowplowing and salting as we do leaf collection, so we need those trucks ready to go out on the road. It takes a full week to pull off all the leaf collection equipment and add on plow blades, salt, etc. In six of the last eight years, our first major snowfall or ice event, which required all plow trucks to treat streets and make them safe for drivers and police and fire vehicles, took place the first week in December or sooner.
