I'm sure that he'd like to thank hiker and author Tami Asars for her advice and for her book, Hiking the Pacific Crest Trail: Washington: from the Columbia River to Manning Park. Powell's Books in Portland carries it: https://www.powells.com/book/-9781594858741
As for me, due to family needs I can't join Dan on this one. I wish him the very best and look forward to hearing from him. Good luck old friend!
