I'm trying to work out a good daily schedule now. Heat is definitely a consideration, as well as getting to shelters before they fill up, or at least early enough that i can keep going if they are crowded. One of the 'rules' I have is no hiking at night, set by my mother, and I need a ride from her so that is to be obeyed. the average civil twilights for the trip( aka when it gets light out/dark out, but before sunrise/after sunset) is 4:42 and 7:07. So I totally dig the idea of getting up at 4 to start hiking. Do you do breakfast in camp, or hike for a while and then eat? Sleep is also very important to me, so that might come into play.
I hiked it last year as a trip that the summer camp I used to go to ran. So it was a group of 9 of us, and all of our resupplies were meeting someone at a road crossing. I'm avoiding resupplying for a few reasons. First, I'd like to maintain the illusion of being in the backcountry. Second, it is simpler without, and third, My parents would have issues with me hitching rides to towns and being in them, they feel much better about me being in the woods(safety wise).
I'll keep an eye out for you, it would be awesome to run into someone. At that point I'll be the famished, tall, long haired, 16 or 17 year old.
Edit: also, what are your thoughts on bear-bagging? I want to keep all of my food, but hanging a bear bag is also annoying and a big time-sink, especially if you are rolling in at or after sunset.
