Before the shops on Lowell's Main Street unlock, the storefront walks have to be down to bare concrete — that is the winter assignment, and Priority Landscape & Maintenance runs it in the dark. Plow the lot, cut the entries open, put salt on the corners where meltwater refreezes by mid-afternoon. In the warm half of the year the same routes turn to mowing and trimming, holding lawns and edges tight through a growing season that pushes hard from May to October. The river fog burns off, the mowers start, and the village looks tended to. Both halves come down to one idea: the place ready before anybody needs it.
