If you hear a loud boom at 6 a.m. Saturday, do not be alarmed. Or, be alarmed. It is just your welcome and wake-up call to the Fourth of July celebration.

This is just one of many activities Saturday that is part of America's Freedom Festival at Provo.Three individual aerial salutes will be shot off from the aerial fireworks mortars just south of Cougar Stadium. Brad Bone, who is in charge of pyrotechnics for the festival, said aerial salutes are basically explosions in an aerial shell. He said residents will hear a loud boom within one or two miles of Cougar Stadium.

"It's like a bomb has hit," said Carl Bacon, member of the board of trustees.

The aerial salutes were once a traditional aspect of the Freedom Festival at Provo that are being brought this year for the first time in about 10 years.

"It's a tradition to wake up the neighborhoods and announce it's the Fourth of July," Bone said. "People always like the noisemakers. It will get the blood going for the Fourth of July."
