About 150 people took over Moccasin Lake Nature Park Monday morning.

"They come in," park manager Cliff Norris said, "like locusts and they swept through the park."

The volunteers from Valpak spent their day off giving back. The employees participated in Martin Luther King Jr. Day of Service by cleaning up the Clearwater park. People pulled weeds, cleared out debris and even helped get rid of non-native invasive plants.

"It's like having 10 employees for a 40-hour week, and more," Norris said. "They did a tremendous amount of work."

Erik Smith is Valpak's Diversity Officer. He said it was important to provide his employees a tangible way to give back.

"The idea of a day of service is a day on, not a day off," Smith said. "To be able to clean or support cleaning a park of this size and this magnitude is just something we thought was important."

Eight-year-old Gabriel DeJesus joined his mother Tammie during this day of service. He used a broom and stood on his tip-toes to clear cobwebs from the buildings.

"It's pretty fun cleaning up stuff," DeJesus said. "You get to help people."
