Can you imagine what BIBE would be like if everything was restricted, no cross country hiking/backpacking. Any time you wanted to go anywhere and see anything, for the most part, you have to be with an outfitter.
They're probably working on that behind the scenes right now.
State or national park....doesn't matter. They both want to highly restrict your activities, thus letting you do only what THEY find acceptable on YOUR public land.
Your taxes (and ever-increasing use fees) pay for all this, but you get no voice in the process as all the restrictions are couched in terms of 'preservation' or 'safety', even when there is no demonstrable impact to the resources, nor any individual duty to any person to ensure their safety. The most perverse reason is 'lack of proper staffing' to manage you. If they can't staff it, you can't use it. You might hurt yourself if not constantly and fully supervised.
Since they charge you for your presence, they become fully liable for injury; unlike under the recreational-use law which shields landowners from liability as long as they allow you free access. Their contractors also are in the liability chain.
