On a Thursday afternoon in July the cottonwoods near Nissen Reservoir stand perfectly still while everything else shimmers. MD Mowing Co. is out in it, mowing, edging along drives and walks, trimming what the deck cannot reach, blowing the paths clean afterward. Bluegrass at five thousand feet takes the sun hard, so the height of the cut is a decision, not a habit. The finish shows in the stripes, laid straight, running the direction the yard was built to be seen from. A lawn that looks intentional is the point of the whole afternoon.
