I suspect this will end when the forest service decides to designate a couple of locations for shooting and hires some people to run them. Other states I've lived in have done this and then had a $25 dollar annual permit to shoot at these locations. The guy that ran the one I shot at regularly wasn't always out there, but the area was open from sun up to sun down 7 days a week. He was almost always there during peak shooting hours, but was pretty liberal about the shooting. It was a win for everyone. Shooters respected the area and cleaned their trash or got their card pulled. Conversely, if you didn't act like an idiot he left you alone. He also had direct access to call for medical or LE if they were needed for injury or altercation.

Until accomidations are made by both sides of this issue, it will continue on an adversarial circle; forest service will continue to close areas like this due to complaints and shooters will continue to find new areas to shoot. It's stupid and eventually the forest service will have to address it as the number of shooters in the front range are large enough to force the issue.
