LinksMags' Quick and Dirty Guide to the PCT
Absolutely the single most helpful source for planning and executing a PCT (or CDT, or Colorado Trail) hike. Do free research on the internet, and then if you decide for real real that you're going to hike, pony up for her book before you do anything else. Every single aspect of planning and hiking is crowdsourced with advice from a dozen or so past thru-hikers, some of whom have widely different methods for how to get the job done. It's all specific to each trail. I've been reading and re-reading this ever since I got it in the mail a few weeks ago.
