Grass is not native to this stretch of Adams County — the land around Derby would rather be shortgrass prairie, the kind that still runs wild across the Rocky Mountain Arsenal refuge just to the east. Growing a green lawn here is a conversation with a semi-arid sky, and M&N Services, LLC holds up its end of it: mowing on a steady rhythm through the long bright summer, edges cut crisp along walk and drive, and cleanups when the cottonwoods down along Sand Creek finally let go. Afternoons build thunderheads over the mountains and drop twenty honest minutes of rain on the block, and by evening the yards smell like a much wetter place. That is the hour the work shows — stripes laid straight, beds cleared, everything squared to the street. This soil will give you a lawn; it just wants somebody paying attention.
