An estimated 400 volunteers turned out on the morning of October 16 for the 7th Annual Hinkson Clean Sweep in Columbia, Missouri, nearly doubling last year's turnout.
"The Clean Sweep is proof that if you organize it, people will show up in droves," says Scott Dye, a Columbia resident and director of the Sierra Club's Water Sentinels Program, who helped organize the event. "It's just one of the many reasons I'm proud to call Columbia my home." That's Dye below with Amy Meier of the Missouri Stream Team, one of the event's co-sponsors.
Volunteers convened at half a dozen sites along the creek, which runs just south of downtown Columbia and the University of Missouri. Everyone was given two bright red garbage bags to fill up, and many people ended up asking for more bags.
Scouring the stream banks and wading through the creek's shallows, participants removed 2.5 tons of trash and more than a dozen tires over the course of the 2-hour cleanup.
