A new sign went up at an oil field entry off of a state Road. No gates, no fences. Multiple other entry roads unmarked. Dropped Pin https://goo.gl/maps/EX9tvKAo11s (Hundreds of acres of oilfield, for those who have trouble with the map link) A few fenced facilities are in the pasture, but are far apart. Also, 3 separate companies operate facilities accessible from this entry point. If you are working for one of these companies, you sign a service agreement that clearly prohibits firearms on site. But Joe Blow public license holders? How can this possibly be enforced?
