There are copies at several libraries, though none of them particularly close to you. But most libraries are pleased to arrange an inter-library loan. Take a run over to the Boise Public Library, or the library at Boise State University. Give them the title, and say "WorldCat" as an index to look it up. (There are several, and they will check them all.) I bet they can have it in your hand in a week. And since it is only 28 pages you might even scan it into electronic format.
