Mysterious Gulf Breeze UFO and Alien Billboard

My Mom shot these photos of a mysterious billboard that asks “When? Gulf Breeze UFO?” located at the entrance to Navarre Beach in Florida, across from the intersection of Hwy 98 and Hwy 87 in front of the Navarre Beach Bridge.

Navarre Beach is not far from Gulf Breeze, which is the location of a famous series of UFO sightings in 1987, documented by Ed Walters and studied by MUFON (Mutual UFO Network).

Does anyone know who’s behind these billboards? Is it to promote tourism or scare people away?
