Sounded like a huge amount of fireworks, approximately 9:40-9:45 pm, maybe down in the Madison Valley. Couldn’t see any flashes, but it was too sustained to be gunshots (I hope!). Anybody know what was going on? It was too early to be 10:10 pm on 1010/10.
UPDATE by jseattle: According to police radio, these were fireworks at the Seattle Tennis Club in Madison Park. The venue is frequently used for weddings and other exciting pyrotechnics.
