I totally get your fast-pack philosophy and what you're going for. It's not meant to be "comfortable". I wish you good weather and good times. I'll be in the region (slow-packing) a few weeks before you.
Someone previously quoted the regulations for the area, and I'd like to add an opposing opinion on their conclusion:
Code of Federal Regulations
Title 36 - Parks, Forests, and Public Property Volume: 1
Date: 2007-07-01Original Date: 2007-07-01
Title: CHAPTER I - NATIONAL PARK SERVICE, DEPARTMENT OF THE INTERIOR
Context: Title 36 - Parks, Forests, and Public Property.
"Camping means the erecting of a tent or shelter of natural or synthetic material, preparing a sleeping bag or other bedding material for use, parking of a motor vehicle, motor home or trailer, or mooring of a vessel for the apparent purpose of overnight occupancy."
They concluded that, "If you walk thru the night and nap during the day, you are not camping.
If you are not camping, a bear canister is not required."
I think that's a slight misunderstanding of the language of the reg. -- in law, commas used in a law/reg. are generally interpreted as an "or", rather than an "and" -- which means that is you erect a shelter OR prepare bedding material -- you are "camping" in the sense of the reg., regardless of whether it's day or night. A NAP would mean that you're just lying down temporarily (without bedding or shelter).
