Saturday morning in Erie begins with sprinklers ticking and somebody's dog barking two fences over, and the yards start filling up with plans. Luke's Scoop Troops keeps those yards ready for the day — mowing, trimming, edging, and clearing the ground so that grass is simply grass again. The high-plains light is generous by nine, hot by two and gone gold along the western rim by evening, so the work moves early and moves quick. Cleanups at either end of the season tidy what the weather dumps in the corners. A yard that is clean underfoot is the whole difference between a lawn you look at and a lawn you use.
