ODEON THEATRE OPENED; LARGE CROWD ATTENDED That was the byline in the Mason County News in October 1928 when Otto Schmidt opened the Odeon theatre. The reporter stated that “it is the most attractive playhouse in this section of the country…and there is nothing within 50 miles that compares equally with it.” The Odeon Preservation Association (OPA) will celebrate the 90 year anniversary of the opening Wednesday October 24 at 7:00PM.
