Mark your calendar for July 10th -- it's Cow Appreciation Day, and Chick-Fil-A is celebrating by giving away free entrees!

I used to live in Oklahoma where Chick-Fil-A is a pretty big deal. I had a colleague who loved Chick-Fil-A so much that one Cow Appreciation Day he took a personal day, dressed his kids up as cows, drove to OKC and hit four different Chick-Fil-A locations for free food at each one. Whatever they didn't eat, they brought home and ate the next day.

That's a true story.

I don't know how much you love Chick-Fil-A, but July 10 this year really is Cow Appreciation Day, and Chick-Fil-A is once again celebrating by giving away free entrees.

How do you earn yours? Simple. Dress up like a cow -- in any way, shape or form -- walk into your local Chick-Fil-A  between open and 7pm, and claim your free entree.

Here are some costumes from last year for inspiration:

And that's about it! Any other details are available at Chick-Fil-A's website.
