We’ve all heard the rumors, repeated over and over again, that Petaluma’s Phoenix Theater is haunted by ghosts. The stories about a “strange presence” in the balcony and wispy apparitions floating around the ceiling are as old as the theater itself. Are they true? Ghosts of the Phoenix Theater, an all-day workshop, aims to find out. Led by Amy Bruni and Britt Griffith from the SyFy Channel’s hit series Ghost Hunters and abetted by Mark and Debby Costantino of Ghost Adventures, the workshop includes lectures during the day and an honest-to-goodness paranormal investigation of the building at night. Bruni grew up at the Phoenix with first-hand experiences at her old haunt, and even theater manager Tom Gaffey makes casual allusion to the theater’s ghosts. Do they exist? See for yourself during the definitive examination on Sunday, July 25, at the Phoenix Theater. 201 E. Washington St., Petaluma. 11am–1:30am. $129. 707.762.3565.
