It's unclear where they bought the fireworks, but a West Richland family said they had no idea they were aerials.

Unprepared for air-borne fireworks, they chose a poor location on July 4th and caught their tree on fire. That led to another, and another.

By the time firefighters arrived a fence and 10 trees were ablaze 30 feet from the home!

But the blaze was contained and all is well.

9 vehicles were damaged or destroyed in Richland that same night and the dike near the Blue Bridge also caught fire and needed a water cannon to be suppressed.
