Downriver is a real place, not just a direction — a string of towns leaning on the same water, with Lincoln Park in the middle of it and the low green channel of the Ecorse threading its southern edge. Downriver Ground Control LLC keeps ground here in both of its tempers: mowing, trimming and edging through the long humid stretch from April to October, then plowing and salting once the calendar flips. The turn can happen fast — leaves still coming down on a Tuesday, an inch on the driveway by Thursday. Working both ends of the year means knowing the same yards in two languages. A tidy summer edge and a bare winter drive are, in the end, the same promise.
