Great Esker Park lifts a spine of ice-age gravel above the marsh, and from that ridge the tide arrives below as silver threads working through the grass. All Things Dirty inc. keeps the yards on the streets that run out from under it — mowing and edging through the green months, plowing and salting once the wind turns. The name is honest about the job: soil on the gloves, clippings on the tailgate, a bucket of ice melt riding in the truck by December. What a customer actually sees is the tidy opposite of all that — an even cut, a crisp line where lawn meets walkway, a driveway wide open before the morning gets going. That contrast is the whole reason to do the work well.
