Colchester Avenue climbs past the hospital and the hill keeps the weather honest — whatever falls up there stays a little longer. MACK Services works both halves of the Burlington year: mowing, trimming, edging, mulch and leaf clearing while the grass is running, then plowing, shoveling, snow blowing and salting once the ground goes hard. The changeover usually happens inside a single November week, mowers off the trailer and plows onto the trucks between one storm and the next. Both jobs finish the same way — a property somebody can walk across without thinking about it. That is the result worth chasing.
