Kolby Kirk is some kind of Da Vinci of the trail. Check this sample page from his 2011 PCT journal.
I saw JEFF THROPE link to that on Adventure Journal:
… After being laid off from his job in April 2011, Kolby Kirk (The Hike Guy) decided he would attempt to complete as much as he could of the 2,650-mile Pacific Crest Trail.
Starting at the Mexican border near Campo, California, he walked for 159 days and nearly 1,700 miles. In that time, Kolby wrote 850 pages in his journals, a few of which he has started to scan …
Kolby is now working on a book …
More samples and links to Kolby via that post.
Adventure Journal was ranked #1 Adventure Blog by Ouside, by the way.

Wow! This is great! I, too, lost my job and hope to hike the PCT and journal, but I could never live up to this level of detail and illustrations. I love the colors. My journal will have to rely on my skill as a photographer.
Go for it, Benjamin.
