On June 22nd, 2013 at Oklahoma City's Cox Convention Center, over 500 gathered for the 2013 Oklahoma Freethought Convention (FREEOK). Speakers included Sean Faircloth, Dale McGowan, Emily Boyer, Zack Kopplin, Seth Andrews and Lawrence Krauss. (Jamila Bey was scheduled but could not attend due to a conflict. She dialed into the conference A/V system, but her presentation could not be recorded for the YouTube videos.)
