There is about a two mile clear stretch view into their property that we'll constantly have motion sensor monitoring and video surveillance to give us a heads up on any possible shenanigans, but from our understanding of local knowledge, the folks we had a dispute with do mostly keep to themselves, and are not particularly well regarded by the ranchers, so, we've played our cards right so far.
Just dig a moat along the property line and fill it with gasoline. This is Texas we're talking about.
But but, with the volatility of gasoline it's going to be a maintenance nightmare to keep it topped up!
