Late April on the ridge above Westfield can still deal out a frost, and everyone here watches for it the way they watch the lake. Westfield Ag & Turf works the ground between those cold nights and the long green middle of the year — mowing on a steady cycle, trimming close along fences and foundations, and taking the yard down to clean turf in spring and again in fall. Grass grows on gravelly lake-plain soil here that drains fast and wants attention; keeping it dense is a matter of showing up regularly rather than dramatically. By August a well-run lawn is a solid, even sweep from the road to the tree line, and that is the whole ambition. Westfield and the towns around it — Ripley, Portland, Sherman and Mayville — make up the service area.
