Sure looks like crooked County gov on the surface, but like CatD we need more info. The guys may be getting harrased for their land, or they coukd be just some more Bundys.
What's to keep them from putting a gate in their own fence 50 feet off right of way? The road looked to have very little ditch at all. County roads in the south have nearly no ditch. Often they are actually below grade and flood easily.
