ALIEN: UFOs in the Hudson Valley

Since at least the 1980s, the Hudson Valley area of New York has been a hotspot for UFO activity. Here, various crafts have been spotted by hundreds of people, leading many to wonder what's so special about this part of the United States. Some think that underground cave systems might be drawing UFOs in. But with the recent unexplained drone activity, it's possible we may have answers sooner rather than later.
