I think most people have one or the other hike specifically in mind. It is so different packing for a backpack instead of a day hike.

I just read a report on another site that the Visitor Center was back to releasing no-show day hike permits at 2 PM (rather than the 11 AM that I thought was the case this year.) So now it is show up at 11 AM for the no-show permit lottery for overnight permits starting the same day.

And show up at 2 PM to go after the next-day no-show permits of day hikers that did not pick up their permits by noon. This is the same as it was in 2010.
