Mike, should clarify. Baker's Box aka Pandora's Box IS the bottom half of the "unrunnable gorge." Both therangelfie.blogspot.com and shane's blog have info on it. Basically only one part is unrunnable (sieve), and the portage around it is nearly impossible, so a lower put-in was scoped. And yes, the locals are running it afterwork.
Private Property everywhere, so a guide is mandatory to keep conflicts at a minimum.
Not to mention walled in and blind V+ whitewater, which is why its so damn good.
