Even the remains of Hurricane Isaac couldn't stop Knoxville's 25th annual Boomsday festival and fireworks show.

Around 400,000 people filled the banks of the Tennessee River and the downtown area to view the largest Labor Day fireworks show in the country.

"The fireworks were a little better this year than the last few," Cason Hewgley, senior in political science, said. "In the past few years, there has been a lot of smoke that hung around from the fireworks being shot off. It was a little windy this year and it helped clear the smoke away and made for a great view of the fireworks."

Rain moved into the area thirty minutes before the show began, but subsided shortly after.

The night was clear and cool as the twenty minute show began; however, rain moved in again around fifteen minutes into the extravaganza.

"The rain didn't really affect the fireworks," Hewgley said. "We did get in the car for the very end, but it didn't affect the quality of the fireworks."

Patrons could view the fireworks from many locations, including from boats on the river.

A large crowd gathered on top of the G10 parking garage next to Neyland Stadium to watch the show.

Spectators arrived and began tailgating hours in advance to make sure they had a great view.

"We moved our car to G10 around 10 in the morning," Hewgley said. "We had a great location on the top of the garage. I've watched it from downtown and other places around the area, but I think G10 is the best location. You have the perfect vantage point."

Cars could be seen with license plates ranging from Blount County to South Carolina and Alabama.

The fireworks show was just the capstone for the day. Boomsday officially opened to the public at 1 p.m. and included concerts sponsored by Q 93.1 and Next Level Wrestling heavyweight championship.

WBIR-TV also had a live broadcast of the event.

During the fireworks show, Star 102.1 - FM played music to accompany the sights above the river.

"For the first half of the show, we had our windows down playing 102.1," Robbie Leonard, sophomore in political science, said. "The music matched up really well. My favorite segment was when they played the Tennessee Waltz and had the slow motion-looking fireworks. After it started raining, we rolled up the windows and got under our tailgate tent. I thought watching the show with music was a lot better than watching it without."

One segment included Rocky Top playing on the radio while orange and white filled the sky. Other portions included pop, classic rock and country.

Even with the rain, attendees said they would be back next year to watch one of the largest fireworks shows in the country.

"I'm from Knoxville and I've been to the fireworks show many times," Hewgley said. "Even though it did rain, I'm still going to come back next year. The fireworks are always great. It's worth getting soaked to watch Boomsday."
