Head south on Bay Street toward the Berkley line and the land flattens, the air thins, and you can feel the river widening somewhere off to the left. K.P Ritchie & Sons INC. covers that stretch and the rest of Taunton in both directions of the year — mowing, trimming, edging and cleanups through the growing season, plowing and shoveling once the storms come in off the water. Coastal snow down this way lands wet and dense, and it wants moving early rather than admired. Lawns want the opposite: patience, a set rhythm, blades kept sharp. Doing both well is mostly a matter of knowing which season you're standing in.
