Unused Reston trucks sincde the last snow-maybbe as long as a month?

A lot of Reston trucks have not been used since the last snow or longer. I'm often seeing four at a time as if Reston workers never ride two or more in a truck. There is some s-10's I'm often seeing on the trails four at a time. The trails are not built to sustain vehicle traffic and as a result of vehicles are often deteriorated, broken up on the edges.
