Query: Hiked the eastern portion

I found his trail guide was terrible. The fact that campsites can be as much as 5 miles apart, with no suitable emergency sites in between meant that I was forced to stop early each day, once a site was found. He mentioned none of this. This book ended up in the trash at the final trailhead. For those of us from the west, this trail is like the jungle, and the book did not prepare me for the dense and dark conditions found along it. Did I mention the poison ivy? Tim hardly does. It's EVERYWHERE.
