UFO Sightings

I wasn't able to attend the recent MUFON meeting in Ely, but fortunately KOLO TV was there and they've filed a story about a recent UFO sighting, including the video footage that the observers took.

I wonder if more UFOs are spotted during the winter, when the nights are longer, or in the summer when more people are outside, even though the nights are shorter. And is that same pattern evident in both the Northern and Southern hemispheres, or do UFOs prefer one part of the planet earth more than another? So many unanswered questions...
