Hi, hope it's in order posting this...
I've recently had a book published, if anyone is contemplating the Pacific Crest Trail or enjoys a 'hiking adventure' read then thought you might be interested in "Dances With Marmots".
2700 miles from Mexico to Canada up through the desert areas and High Sierra Nevada of California and the Cascade ranges of Oregon and Washington. Could be of added interest in that it looks at the US and its wilderness through the eyes of a Kiwi. (New Zealander) 
Anyhow, if interested, more details at http://www.danceswithmarmots.com
Cheers, Geo.
