Lawful fences.

SF 73 updates Wyoming's fence laws to clarify responsibility when livestock damages property. It increases fines for unlawful wire fences and changes liability from "animals" to "livestock" for damage claims. For subdivisions, it requires adjacent landowners to pay half the cost of perimeter fences (not full cost), while the subdivision covers additional construction expenses. This directly affects ranchers, landowners with fences, and developers building near grazing areas.
