I imagine it is, but they put up the signs on the fences on both sides of the road, which is their property and it is illegal to trespass. IANAL, but on undeveloped land in the US you have to put up 'no trespassing' signs generally before enforcing people not to trespass on your land. I reality the ranchers(in reality they are usually rich sport ranchers that live in a city and recently bought the property) don't even need the closed gate in most cases. If you are in the middle of nowhere going down a dirt road and you come up to a fence that crosses the road with a cattle guard and on both sides of the road it say no trespassing, what do you do?
