From the high ground on the moraine you can watch a McHenry snowstorm arrive — a gray wall coming in over the fields twenty minutes before the first flake lands. Highpoint Landworks Inc. uses that head start, staging trucks so driveways and lots open early instead of late. The routine is plowing, shoveling walks and entries, and salting the ice that forms once the wind lays down and the temperature drops. Snow gets pushed and stacked where it will not block a corner or melt back across the pavement. Winter work runs through McHenry, Prairie Grove, Crystal Lake and Woodstock.
