I can give you tangible results:
In 2015, RMEF was instrumental in killing the attempt to zero out Habitat Montana. They did so by sending an alert, and working diligently behind the scenes. That alert generated hundreds of comments to the legislature. They also weighed in on the transfer of public land issues and helped ensure that their membership was tuned in to what was happening. Their advocacy helped kill the transfer movement in Montana.
Throughout the season setting processes over the last 13 years that I was aware of, RMEF worked closely with the local chapters to bring comments to bear that helped ensure better outcomes.
When RMEF endorsed the Roadless Area Release Act in 2012, they quickly reversed direction after more detailed analysis and their efforts there killed a bill that would have eliminated the Roadless Area Conservation Rule throughout the United States.
In 2017, RMEF CEO David Allen was a speaker at the Public Lands Rally, as was KC Walsh (current commissioner) despite being pilloried by some groups and people.
RMEF may not have social media all over the place on this stuff, but it is critical to remember that just ecause you don't see something on social media, does not mean that there's nothing happening. I'd love RMEF to toot their own horn more on the state level stuff they do, because it's generally well developed and thoughtful approaches, versus storming the castle. Both have their place, and given RMEF's mission, size & approach, I think they do a good job.
Even when I disagree with them, which happens from time to time on policy, or like when they were advocating for a constitutional right to hunt and fish that we were opposing due to concerns about private property rights. I never had a angry conversation with them when we were debating the issue, and at the end of it, I think everyone had a much better understanding of their approaches, and how effective they can be.
