Some US cities have replaced fireworks with light shows performed by drones. Drone shows reduce the chance of wildfires and sound pollution. Lakewood, Boulder, and Castle Rock have opted for drone shows following the switch from other surrounding cities in Colorado last year. Some fireworks shows were canceled this year. Aside from noise pollution, fireworks are a leading cause of wildfires in many dry cities.
