SAN ANTONIO (KTSA News) — It was a cool late September Saturday night in Michigan that turned real steamy…. but it had nothing to do with the weather.

Somehow, a pornographic video was playing on a giant digital billboard near Auburn Hills.

The sky took on an unusual red hue as drivers on I-75 hit the brakes when they spotted the video.

Some were shocked, some were amused and some were… aroused.  But it’s probably safe to say they were all intrigued and wanted to know why the movie was showing on the billboard.

Police are still trying to figure that out.

A company called Outfront Media operates the billboard. Once they found out the video was playing, they took it down.
