The event will have around 550 shells going off tonight for the 4th of July.
These large shells will set off fireworks that will launch 8 to 900 feet in the air and expand by about 1,000 feet across.
“We have about 7 hours on the set-up, and we’ll probably have the same amount of time on tear down,” said Lee Finlayson, the lead pyrotechnician for Western Display Fireworks. He says he’s set-up for the event for the past 34 years.
“This show is so big, we can’t hand light it anymore, so we electrically fire it. It’s not through a computer, it’s run manually and we have full control of it.”
