TULSA, Oklahoma -- The Tulsa Zoo's annual HallowZOOween continues through Sunday night. Enter - if you dare - from 6:30 to 8:30 p.m. Friday, Saturday or Halloween night.
The trick or treating event offers area families a safe and friendly place to celebrate the season.
Volunteers with the Tulsa County Sheriff's Office and City of Tulsa 911 Communications Center will be on hand. This year, the employees are dressing up as cast members from The Wizard of Oz - and performing some of the songs from the musical.
Each year more than 15,000 children attend HallowZOOeen. The Tulsa Zoo is located at 6421 East 36th Street North.
