I have Inyo N.F. contacts. (They like to get the info out to the public in as many ways as possible, and this forum helps. So passing on the info helps them.)
They are working on better-defined details regarding walk-in permits and parking. But the no-parking-permit part sounds pretty sure.
Actually, if everyone who parks up there MUST have a permit, and you don't get one, verbal affirmation should be enough.
