The Kelso High School production of the classic “To Kill a Mockingbird” has been extended through this weekend, with performances tonight, tomorrow and Saturday. They lost a performance last Saturday, due to a conflict with the annual Kelso Powwow. Performances are being held at 7:30 pm tonight, tomorrow and Saturday, along with a 3 pm matinee on Saturday. The doors to the Kelso High Auditorium open a half-hour prior to the curtain. Tickets will be available at the door.
