One of the reasons the Klamath farmers won a few battles is the website Klamathbasincrisis.org. You need to get a site up that focuses on your issue and presents information to people so that they can support you. Its work, but its worth it. The klamath site was getting thousands of visits a day last summer,and they even had live video donated so we could watch the headgates with them. You surely would get visits to your site by mentioning it on freerepublic, and help will come out of the woodwork. You can't do it alone and you can't do it by trying to fix things through the government process. Its already been subverted by the regional councils.
Funny you should mention using a website. We actually have one in its early stages. The focus is not specific to greenways, but rather on all these local government initiatives, how they are tied together, how they trample our rights, and how they are tied in to broader national issues.
It is our hope that the site will wake up enough local people to convince local government that they need to back off and stop trying to ahead of the pack in implementing all the Agenda 21 stuff.
Luckily for me, I have a few local freeper allies now, so I no longer have to fight the battle entirely alone!
