You want free PCT maps, then go to Halfmile's website, http://www.pctmap.net/ , and download the pdfs and print the sections you need. It covers most of the JMT too, except the portion the heads into the valley from Tuolumne. His maps are better than just about anything else that costs mucho bucks. And it is not full of errors, as are some of the super high priced map-based guides. Save yourself about $200 and spend the money instead on paper and ink. The maps are much more useful than the tiny maps found in the super high priced guides.
That is all... for now.
