Where Clifton Park runs out toward Crescent, the wind comes off the open water and the river flats and lays a hard crust over everything it touches. January nights like that are when THG Property Solutions is working: blade down, beacons on, one property to the next until the list is finished. Snow here arrives as a foot of dry powder or as three wet inches that take the whole morning, and the plan changes to match. What does not change is that people need to get out of the driveway at six. THG clears snow in Clifton Park, Crescent, Halfmoon, Waterford and Mechanicville.
