Your fence holds against the open-prairie wind
Out here the wind writes the spec. Peculiar's new subdivisions sit on stripped prairie with no mature trees to slow a gust, so the footing — not the boards — is what keeps a fence upright. Every post drops 36 inches into wet concrete on a belled base, below the frost line and past the disturbed builder fill. The job we get called for most out here is straightening someone else's 18-inch post the wind already won.
