On Saturday several of San Angelo’s museums will offer free admission and special programs to celebrate National Museum Day, an event sponsored by Smithsonian Magazine to note the contributions made by the nation’s museums and cultural institutions. Museums and facilities with free admission will be Fort Concho, the Mayer Museum, the San Angelo Nature Center, and the Railway Museum. Fort Concho will be having a special demonstration of sewing, talks on the roles of women in the late 19th century, plus specially assigned guides in several of the historic buildings. The recently opened Mayer Museum, on the ASU campus, will have special games and scavenger hunts for children. The Nature Center will offer a dinosaur/animal color craft kit available on-site or for pickup while supplies last. The Railway Museum of San Angelo will feature living history tours led by appropriately dressed conductors, engineers and dispatchers.
