Here's a link to a thread at Mountain bike Review about a lawsuit by the Sierra Club against State Parks over the proposed general plan for Nisene Marks State Park. If the Sierra Club prevails, it will result in a ban on mountain bikes above the steel bridge in Nisene Marks, and would also close the Aptos Creek fire road that many folks use to access the top of Soquel Demonstration Forest.
