Ethan travels from Kalispell MT to WA, but makes a visit to Glacier National Park, which was still closed when I tried to visit it in 1981.
He also hotwires his van to provide new air conditioning from Walmart. He is enduring the Pacific Northwest heat dome.
He winds up at the Hoh Rain Forest in Washington state.
