It starts with a cold engine and a pull cord, the mower deck settling into its line, hands reading the grade of a yard before the first pass is even finished. Grizzly Landscaping LLC keeps lawns mowed, trimmed and cleaned up through Rochester's green months, then turns to the plow when the Lilac City goes white and the drives need opening. There is a plain satisfaction in it — the cut holding its stripe against an old brick mill wall, a walkway scraped clean while the Cocheco still steams at first light, a driveway clear before anyone has to ask. They work Rochester and the towns gathered around it, out where the ground rolls off the seacoast plain and lifts toward the hills, and every yard they leave holds its season a little better than it started.
