If you want to strive for some good luck on Friday the 13th, as well as a free meal at Chick-fil-A, you can participate in Cow Appreciation Day.

The fast-food chain, which has a location on Epps Bridge Parkway, is having a special promotion. Customers can score a free meal at the restaurant by dressing "head to hoof" as one of the restaurant's famous cow mascots. Or, you can get a free entree by simply wearing some type of cow attire, according to a company news release.

Patrons can even get help with their costumes via a special download at a special website. Also, the company will have a special iPhone app for the event. And that day also will have a Best Cow Costume event.
