There are maybe two calm hours in a western Oklahoma morning, and Griffitts spraying knows exactly where they sit in the day. Hinton's spring arrives with a rush of henbit and dandelion across every yard on the section roads, and the fix is timing — weed control and fertilizer put down while the air is still, before the wind gets its hands on the day. Along US-281 the country runs to gypsum ridges and wheat stubble, and a treated lawn in town reads unmistakably against all that pale ground. Mowing, trimming and edging carry the rest of the season, with the yard kept even instead of patchy. It is ordinary work with a visible result: grass that comes back thicker every round, and a boundary at the sidewalk you could sight down.
