For people holding reservations for a Mt Whitney overnight hike, their deadline to show up and claim their reservation is 10 AM.
So after that, the no-shows' permits should also become available.
Harvey, you were there at 9 AM, while some parties had already picked up their permits and dropped a few people off their permits. So I think you got two of the three of those available.
I sure hope I can get all this information clarified pretty soon.
