Cascade Summer is the story of Bob Welch's 2011 attempt, along with his brother-in-law, to hike the length of Oregon's spine. To reconnect with his past. And to better understand the 19th-century Cascade Range advocate John Waldo, the state's answer to California's naturalist John Muir. Despite great expectations, near trails end Welch finds himself facing an unlikely challenge. Laughs. Blisters. And new friends from literally around the world-his PCT adventure offered it all. But he never foresaw the bittersweet ending.
