GEOQUIZ: What town in New Mexico hosts an annual UFO Festival?
Answer: Roswell. The long-running festival (the next one is June 29-July 2, 2017) was sparked by the July 1947 UFO Incident. A mysterious flying object crashed on a ranch north of Roswell and was first identified as a "flying disc" and later as a weather balloon. Conspiracy theories have raged ever since.
