... Nice rant, hired!

Unfortunately, one of the first things that you will learn is: The vast majority of "wheelers" don't care.

Example; when a decision is being made, input is requested, notices posted on all forums, the actual number of letters that arrive is embarrassingly small. If the level of "care" is so small that they can't be bothered to type a few words, send an email, what does that say about bigger commitment?
I agree that lobbing is needed, there are groups that have done that for years. But, it is very expensive and IMHO to be effective needs to be done on a national level, in a united front, like Blue Ribbon. It is an external pressure, like me having a meeting with the ranger and giving a piece of my mind, talk is cheap. IMHO working with/supporting one of the existing organisations would be more beneficial than starting new, further fragmenting the effort?
A few of us have been working with local agencies, attempting to identify things that can be effective. They are government employees, like most, trained to do their job within the agency framework. The idea of relying on, working with outside groups, volunteers is foreign to them and at first, met with resistance. This is somewhat changing and I think it can be beneficial on the grassroots level.
Agree that just going out and picking up some cans has little/no effect, that doesn't mean that I'm going to stop doing it. When the agency notices, it is likely attributed to a "green group". If it is done by working with the agency, on projects that are important to them, then they see that groups care and can be counted on to make a difference with EFFORT. Effort trumps talk!
The agencies mostly see users a evils that they are tasked to deal with. If work is done with the agencies, solving problems that they have, we gain internal allies. They may start seeing us as assets, rather than a problem. IMHO, internal allies applying pressure trumps external pressure.
Yes there is one group of 'users". But, the agency people that I deal with are well aware of the sub categories and the efforts or not, that they use to attempt at solving the problems. Shooters are seen as the biggest problem and no effort is being made from the big shooting organisations to mitigate, admit, reduce the problem. My guess is; we will loose the privilege to target shoot on public sooner than later.
Mesa Tonto is starting to come around, have ordered some supplies, like trail and trail head signs, etc, earmarked for volunteer install. They are starting a program of training/certification, so that volunteers are qualified/certified to use government equipment. The upcoming training will include, first aid, CPR, government drivers/equipment operator licenses, radio certification, trail maintenance/repair, etc and general knowledge stuff like; plants, geology, ruin, mine history, etc.
This is very new and there are still some hurtles to overcome. But there are going to be some projects coming up that I believe we need to get behind 100%. There are proposed plans of not only cleanups, but construction projects, civilian patrols, trail assessment/repair, etc.
The agencies communicate, so if we can make a difference with a receptive one, the word will spread. IMHO this can make a difference without a huge expenditure/$$$, only effort.
