Last I read, in Washington State, if you allow the public to recreate on your land, without charging a fee, you do not have a liability problem.
If you charge a fee you can be held liable. Will the law prevent a lawsuit, hell no! There are far too many sue happy idiots in the world and there are many many other angles they can work besides getting around the recreation clauses.
The BLM is the place we need to start. I would like to invite all interested parties to the next Eastern Washington Resource Advisory Committee Meeting in Spokane at the BLM office 1103 N. Fancher Road, Spokane, Washington around the middle of April (I have not received the actual date yet but will post it when I get it).
The meeting starts at 9 am and is open to everyone. We usually take public comments about 11 am.
I will see if we can get the Juniper Dunes on the agenda for a more formal discussion.
The Eastern Washington Dirt Riders are working on the situation as best they can. One solution is a possible lawsuit brought on by whom, I don't know, against whom, I don't know but perscriptive easement or other ideas are being tossed around. Maybe we need to get the NMA and other interested groups to raise some $$$ and sue the BLM for misuse of funds by buying a property with no legal access to it.
I know I wouldn't buy a piece of land without a way to get into it. How stupid could it be?
