Residents of the Kirkland/Bothell/Kenmore intersection have reported mysterious booms echoing at all hours of the day and night for years. They come at random times, sometimes months apart, and are loud enough to cause people to post inquiries on their neighborhood social media groups en masse asking “did anyone else hear that explosion?!?” and, for those who have never lived in a major metropolitan city, “was that a gunshot?”. No explanation has ever been provided.
