Dallas Zoo extends its drive-thru light show due to high demand

After a popular first run, the Dallas Zoo is extending its drive-thru light show.

Since the start of Zoo Lights at the beginning of December, the zoo sold 24,000 tickets. That's almost double what it expected.

The holiday light show has been extended through Saturday, January 9.

The zoo also started its Penguin Days, which means $8 general admission tickets for the next two months.
