North Berthoud has been filling in with wide new streets and young trees out toward Heron Lakes, open ground where the wind gets a running start at every driveway. TNT Colorado covers both halves of the calendar there: mowing, trimming, edging and cleanups while the grass is growing, plowing, shoveling and de-icing when it isn't. New turf and new pavement both take some learning — where the water runs, where the drifts set, where the sun lands at nine in the morning. Learn a property once and it gets easier every year after. Neat lawns in July and open drives in January come out of the same notebook.
