At around 2 a.m. on July 4, 1977, a woman and her eight year-old son were driving south on I-35 between Oklahoma City and Moore when the woman saw what she described as a “revolving restaurant” traveling across the sky. Later, when relaying the account, both mother and son drew the same disk-like object, traveling at an angle [from Strange State: Mysteries and Legends of Oklahoma].
