They aren't in it for the money, prestige, or even community service hours. They're in it to win, and clean the city up in the process. College of Charleston's annual Dash for Trash returns this Saturday Oct. 24. Each year, students congregate at Liberty Square (in front of the Aquarium) at 10 a.m., separate into groups of about 10, grab a grocery cart, garbage bags, and gloves and dash into downtown looking for the biggest, smelliest, and least appealing trash. Most items hold a point value, with certain pieces carrying more weight than others — cigarette butts, dog doo, hub caps, and batteries are just a few sought-after items. At the end of the competition, the team with the most points, recyclables, and spirit win prizes. The event is co-sponsored by the College of Charleston Center for Civic Engagement and Keep Charleston Beautiful.
