Hornsby's Halloween Boo-tacular is set to begin at ONEOK Field.
There will be 15 trick-or-treating stops from local shops, a costume contest, and Game 4 of the World Series playing on the videoboard starting Saturday night at 7.
Gates and concessions open at 6 and the event is free. Everyone is required to wear a mask while entering the stadium and while walking on the concourse. Organizers say once you are in your seat and physically distanced you can take off your mask and enjoy the baseball game.
