CASPER, Wyo. Video shows the ski and Biathalon trails were vandalized by six people driving on them, leaving deep ruts in the recently leveled trail.
Cameras picked up footage of three vehicles- a Chevy Crew Cab, a Honda CRV, and a newer model Jeep.
These deep ruts are dangerous to skiers or anyone walking through.
Casper police are investigating and urge anyone with information to call.
