As a research geologist, working in the western US has generally been great because of so much easy access to a large amount of public land. But, over the last 5 years or so, I have noticed more ranchers gating off roads going through their land. This is especially annoying when they have a small in-holding in a national forest or BLM land and the road that has been used for over 100 years is now blocked. Most times there is a new (closed, but not locked(that would be illegal)) gate and a big sign that says no trespassing.
One can legally open the gate and use the road and it won't be trespassing, but most people won't know this. Even if you think you are in the right in going onto someones land, confronting an armed rancher is something most people will not risk doing. I generally don't. It would be nice if there were signs that made it clear that it is legal to pass through such gates, but I imagine they would be removed by the ranchers immediately. I'm glad at least some forest service employees are pushing back on this practice.
