In 2012, the Foundation Beyond Belief international team acted as a rallying point around which local freethought, atheist, and secular humanist groups created teams to participate in Light the Night Walks and Atheist Community of Tulsa accepted the challenge. On Saturday, October 13, members gathered at the Oklahoma Aquarium to walk and raised over $500 for the Leukemia & Lymphoma Society.
