Mari Kempton (Fiona "Fenn" Rainbow Crispus-Wellsby) and Carl Schroeder (Zorro Anderson) wrote "The Fenn and Zorro Letters" in 2000. The U.S. Postal Service delivered all the letters safely. In 2023 Schroeder continued the story in a spin-off novella titled "A Letter from Yzabeth." Further adventures may be forthcoming.
