By Tuesday night, hundreds of communities across the Las Vegas valley will be lit up with fireworks.
But make no mistake – the majority of those displays will be of the illegal variety.
Capt. Richard Fletcher of the Las Vegas Metropolitan Police Department says every year authorities warn residents to stay "Safe and Sane," but this year he says they're taking things a step further.
"We're actually sending officers out and looking for illegal fireworks," said Fletcher.
The Department this year even developed so-called Fireworks Squads that will dispatch throughout the valley on the Fourth.
They will be citing violators, but mainly they want to warn residents of the risks.
Late Sunday night, fire crews responded to a 9-1-1 call. Illegal fireworks ignited a bush, that then spread to the attic of a home. A family with children were home at the time.
Homeowner Miranda Bowles said, "Just imagine if we went to bed. We would have burned up in there."
This year, with conditions especially dry, police want to remind people to celebrate smart. Illegal fireworks, they say are capable of causing extensive property damage, serious injury, or even death.
