If you mean the very rugged Pacific Crest Trail, yes I've hiked several parts of it in the High Sierra mountains, California.
If that's the trail you're thinking of, post your tentative thoughts on what portion of it you'd hike (it runs from Canada through Washington, Oregon & California to Mexico) and Ill comment if I have experience near your location of interest.
There's a good little book with a bear on the cover by a guy who hiked the Appalachian Trail, but I don't remember its title. Anaway, it pretty much tells a similar story as for the Pacific Crest Trail.
