The truth: James is right. On a related note, if you google "witch's castle forest park" you'll find many, many more examples of Witch's Castle being misunderstood. (Trading post from the 1600s!)
This blog is dedicated to the stories and overheard conversations of people who know all about the City of Roses and its history. And get it hilariously wrong. Got a story? Heard someone who has misunderstood Portland? Send 'em to me at pdxmisunderstood@gmail.com.
