Every October the snow line comes down the foothills west of Windsor a few hundred feet at a time, white creeping toward town while the lawns here are still green and still growing. Green Mountain Lawn Services LLC covers both sides of that line: mowing, trimming and edging until the grass finally quits, then pushing snow off drives and sidewalks once it is Windsor's turn. The crossover week is the strange one — mower running in the morning, blade on the truck by evening. Working a place with two full seasons of labor in it means never quite putting the year away. It also means a property is handled twelve months out of twelve.
