Frazier, Deborah. "Japanese-American recalls father held at Colorado camp", Rocky Mountain News, December 7, 2006. Accessed July 23, 2007. "Okubo said John Hopper, who became a history teacher at Granada High School about 15 years ago, transformed local attitudes about Camp Amache. Hopper said he wanted to give students a sense of local history, so they began gathering photos and interviewing Japanese-Americans who had been at Amache. We've taken our presentation to schools and colleges across Colorado, he said. It's controversial because some people still think it was the right thing to do. Hopper's students worked with Sen. Wayne Allard, R-Colo., Sen. Ken Salazar, D-Colo., and Rep. Marilyn Musgrave, R-Colo., to win National Historic Site designation."
