William Sullivan is already one of the most accomplished hikers in Oregon.
And he clearly goes back and checks on the places he hiked in the past.
The result: a Fourth Edition of his book . With 18 hikes mapped out in the Eastern Siskiyou Mountains alone, this potentially represents years worth of hiking for the ambitious traveler. William comes out of the woods long enough to call in with the latest on his activities and the updates to the book.
