West of Greenfield the Mohawk Trail begins to climb, and in a December storm you can watch the weather thicken as the road goes up. Lobos Tree Service plows down here in the valley — driveways cleared end to end, parking areas opened, walks and steps shoveled, sand or salt worked into the glaze. A storm that drops eight inches at once is easier than four that arrive over sixteen hours; the second kind means coming back. Snow gets pushed where it belongs the first time, so the banks aren't creeping into the driveway by February. What people notice is simply that the way out is open when they need it.
