In the hollows south of Bolivar the sun comes over the ridge late and leaves early, and grass grows in whatever hours it is given. Sisson's Chain Saws & Stoves, Inc. keeps those lawns cut on a regular turn, working the pitch of yards that never sat quite level to begin with. Trimming finishes what a deck cannot reach — around posts, steps and the base of the maples that shade half a yard by four in the afternoon. Seasonal cleanups clear the sticks, cones and pressed-down leaves that come off the wooded slopes on every side. It is the sort of work that shows most in a single glance from the road.
