May in Greeley can lay three inches of wet snow across blooming lilacs and be gone again by noon the next day. Co. Columbine Lawn Care Service LLC. works both halves of that sentence — mowing, edging and cleanups when the grass runs hard through spring, plowing and shoveling when winter overstays its welcome. The high-plains year isn't tidy, and yards here need someone who doesn't mind switching tools mid-week. A lawn cut evenly and a drive scraped clean: two small orders imposed on a big, changeable sky. Greeley and the towns around it — Evans, Eaton, Lucerne and Ault.
