Quiet blocks off 20th Street give themselves away in small things: a walk blown clean, a gate latched behind, no grass left sitting in the gutter. Courtesy Lawn & Tree Care Inc mows, edges and trims through Greeley's growing season, then clears the leaves when the maples let go in late October. A yard is where a house meets the street, and leaving it neater than you found it is most of the job. Summers here run long and lawns are kept alive by hand and habit, so a steady schedule matters more than any single visit. Serving Greeley along with Evans, Garden City and Milliken.
