One hundred years ago this Saturday, a young pilot named Fred Wiseman delivered three letters from Petaluma to Santa Rosa by airplane, thereby completing the first airmail flight in history. Never mind that he crashed along the way—it’s still an honor for Santa Rosa, where Wiseman bought parts from a local bicycle shop to build his plane after visiting the Wright Brothers themselves. In conjunction with the exhibit ‘Post By Air,’ a live simulcast discussion with Smithsonian curators about Wiseman’s famous flight takes place on Saturday, Feb. 19, at the Sonoma County Museum. 425 Seventh St., Santa Rosa. 11am. $2–$5. 707.579.1500.
