Officials at a small Twin Cities museum hope to re-open in August after 9-11 forced them to close. The Minnesota Air Guard Museum had to return its hangars and exhibition space to the Air Force. Our next edition of "The Enthusiasts" features volunteer Ray Peterson, who has devoted thousands of hours to the museum over nearly 20 years. The museum's displays feature the Minnesota Air National Guard's history, aircraft, and a rare "Blackbird" spy plane.
