The BLM(Bureau of Land Management) is always coming up with L.U.R.'s(Land Use Resolutions), and Travel Management Plans. the best way to fight these are to get involved when they are doing their impact studies(its the only time you really have any say in the matter, and you bet the people that want the lands closed to motorized activities are there). There always seems to be a lot of complaining when they finally do issue their LUR's, but no one was there in the beginning. I have been to quite a few here where I live, and its tough to stand alone(I am notified of meetings, so I know when they are coming). get everyone you know to come with you. We, as a community of outdoorsmen, need to band together(and I mean stand together), to stop most of the closures. Its the only way guys. there are some that are gonna get closed no matter what is done or said(new housing developments, annexations, sale to private owners, etc), but the public lands need our support to keep them open to everyone(including us). get involved and you'll see a difference in how things are being handled now.
