7:35PM October 31, 2017, The Living Desert, Palm Desert, CA My wife and I are members at our local desert zoo. The zoo puts on a "Howl-o-ween" event where thousands of kids, parents are members are invited to walk about and participate in themed mazes, see animals eating etc. We'd been to the zoo a dozen times in the last year and know it well. Tonight they illuminated the adjacent fenced off rocky hill for the visitors to view the resident rams. Shortly after I took a photo of the hill with moonlight clouds above, I saw the end of the cloud cover was nearly directly overhead and that the stars were peaking through. It was only 10 seconds after gazing upward that I saw what looked like two faint stars flying from the clear SW sky, travelling parallel to each other but not in an exact straight line. One of them was pulsing slowly a bright white color, the other appeared to fade in and out, they could have been mistaken for satellites or planes if they had not drifted and slowed to a standstill almost directly overheard. At this point I called to my wife, got out my smartphone (which couldn't capture anything of course) and we both saw the orbs slowly stop. At this point another orb slowly appeared and then the three balls of light seemed to "align" themselves into a classic UFO triangle. At this point, shocked, I looked around to see how others were reacting and their were dozens of people all around us but, as expected, they were completely engaged with their costumed kids. The triangles altitude was not much higher than the low-hanging clouds yet their appearance was inconspicuous enough to just appear as other faint stars. We could see that they weren't exactly still but hovered in place, not pulsing or fading in or out, but just staying still as if "pretending" to be stars. After 3 or 5 minutes staring up at the floating triangle, we had to get going, reluctantly. It felt like winning the jackpot then having to leave your lotto ticket behind. I was not too surprised by any of this behavior as I have researched many other UFO cases that are nearly exact replicas of this, yet the sheer euphoria and shock of seeing it right before your eyes, out in the open in front of thousands is a power emotion I'll never forget. Researchers and witness have concurred over the years that whatever intelligence these orbs have, it is probably aware of how humans think, and show themselves only just enough for a few to see them, but rarely make an appearance big enough or at the right time for a full-scale sighting with any real earth-shattering consequences. This being my second sighting, and my first in what must be the most populated public outdoor place for the next hundred miles, I believe the UFO definitely knew it could act with impunity.
