Kennywood tests out its holiday light-up display on Tuesday. On Friday, following Thanksgiving, Kennywood's Holiday Lights will be open to the public. The event boasts Pennsylvania's tallest Christmas Tree (90 ft.), pictured here, and will run every Friday, Saturday and Sunday night from 5:00 p.m. to 9:00 p.m. through Dec. 23.
