Rather celebrate the sweetly spooky side of Halloween than the ghastly and the goulish? Costumes, a Halloween musical by local actors and musicians, might just be the thing for you. The audience is encouraged to come in costume, and the garden with a lighted walkway will be open for exploration during intermission. Tickets are $10, which is donated to Tulsa Garden Center. Make reservations by calling (918) 746-5125. Find the show in the Linnaeus Garden Barn at the southeast corner of Woodward Park.
