Talk about a grand finale.

Spectators at an Arizona fireworks display Monday got a little more than they expected when the show ended with a bang — a wildfire.

The blaze sparked near the very end of the 11-minute display at BlueWater Resort & Casino in Parker.

“Fireworks at BlueWater were great, then the desert started burning,” a casino employee wrote online, according to ABC11.

The casino later wrote on Facebook that the fire was brought under control and no one was hurt.
