WOONSOCKET — Jason Cropley usually gets off work in the morning, but when his graveyard shift ended Monday he had another job to do: free his car from its prison of snow.
Cropley, a security guard at Portola Tech, thought there might be trouble when he heard the rumble of snowplows passing the Fairmount Street mill with increasing frequency during the night. Sure enough, they buried his car, parked just a few feet from the edge of the road, behind a knee-high wall of grayish, lumpy snow.
