Early fog lifts off Spring Pond and sits in the hollows of Peabody until the sun burns it back, and for one hour the whole city looks like it is only just waking up. Mystic Property Services is usually already out in it — mowing, trimming, edging and haul-away cleanups while things are growing, then plow routes, cleared walks and salted entries once they are not. Residential yards and commercial properties run on the same principle: get there before it turns into a problem. There is a real pleasure in a place that is ready before anybody arrives. That early hour is where the work belongs.
