According to Chick-Fil-A, 1.95 million people participated in last year's event.
On Tuesday, July 9, the restaurant chain will give away one free entree (salads excluded) to any customer dressed as a cow. You can dress head to hoof in full cow costume.
It's time to break out your black spots and cow bells.
The celebration will last from opening through 7 p.m. At locations serving breakfast, options also include the Egg White Grill, Chicken, Egg and Cheese Bagel and Chick-n-Minis.
Chick-fil-A is famous for the "Eat Mor Chicken" cows, and this year's Cow Appreciation Day marks the 24th anniversary of the marketing campaign, Jon Bridges, Chick-fil-A's senior vice president and chief marketing officer, said.
The completely fictional but fun holiday is being celebrating tomorrow at Chick-fil-A and it's your chance to grab some free food. For a list of ideas or to see eligible items, visit Cow Appreciation Day online.
