According to Don Herron's The Literary World of San Francisco & Its Environs, Bay Area Forteans frequently met at 478 Union Street. This housed the Pencraft Writers Studio, run by pulp authors Kenneth MacNichol and Polly Lamb Goforth. (Goforth was also a sorceress who used the same form of magic as Haas.)
