Wind crossing the open corn ground above the Thruway does not need much snow to build a drift, and by dawn a driveway can be filled in twice over. R & R Property Services plows through that, clearing drives, lots and walkways across Schodack and coming back around when the wind refills them. Exposed properties get watched more closely than sheltered ones; that is just how the ground here behaves. The work is quiet and mostly finished before anyone is up. What it leaves behind is a clean apron of pavement and a way out to the road.
