So no wonder that Portland is enchanted with a coven full of celebrations next weekend. Maine Today has the most comprehensive event listing, including: Spirits Alive Walk Among the Shadows III Evening Tours of the Eastern Cemetery, Portland Improv Experience SPOOK-tacular Halloween Monster Mash at The Maine Studios,"The Legend of Sleepy Hollow" performed by the Portland Ballet Company at the John Ford Theater, SPACE Gallery Halloween Party, "Rocky Horror Picture Show"at the State Theatre, 1st Annual Zombie Bash at Port City Music Hall, Nightmare Halloween Costume Party presented by PortSports Social Club at Two Point Gallery, Nightmare on Mayo Street Haunted House at Mayo Street Arts (see image above), and Sid Tripp's Halloween Bash 2010 at Mariner's Church.
