We've all been reading the story of the triangle shaped UFO out near the Twentynine Palms base (link in comments). I got curious and wondered how many triangle UFO sightings have been reported in the vicinity of any Marine Corps base. This is a map based on just that, sourced from militarybases.com and NUFORC. Twentynine Palms is the highlighted circle, and each circle is 100km. There is a high concentration of triangle UFOs spotted in southern California overall, including Twentynine Palms.
