 For the second year in a row, Mill Creek residents saw drones, not fireworks, light up the sky. City officials say safety was the reason for the drone choice. Cities such as Mill Creek are opting to have drone aerial shows as heat and dry conditions make shooting fireworks more risky. Mill Creek puts on their show at the city center, which is near commercial and residential areas. The cost to taxpayers for the drone show is about the same as fireworks. Officials say the city collaborates with a drone company to design the show.
