I once lived in Arizona near Fort Huachuca, an Army installation. Our street was lined with mobile homes, each with a small yard. In that arid climate, grass struggled to survive, especially with the constant play of children and dogs. However, one lawn stood out—vibrantly green, lush, and adorned with neat rows of flowers. I couldn't understand how the owner achieved this until I spotted a sign in the yard. It read: "Danger — Minefield."
