Ehh I wouldn't block the road. The property owners might want in and some jackhole might start a fire and the department might want in. The cattle lease holder might want in to feed or check on the cattle as well. Leaves you open to some vandalism as well, some people just think since they have been trespassing there for years it is there god given right to keep doing it. Some people also just road hunt and don't know that road ends in a gate and it is pretty hard to turn around in there as it is.
