"I think it's become a tradition [for spectators] to leave their trash behind. It's kind of like movie-theater syndrome," Ann Erdman, spokeswoman for the city of Pasadena, Calif., told the San Gabriel Valley Tribune.
The 70-person Pasadena Department of Public Works is tasked with collecting the 65 to 75 tons of trash left along the 5.5-mile parade route. According to the Tribune, crews start at either end of the route, removing large items that might impede foot or car traffic. From 10:30 p.m. New Year’s Day to 7:30 a.m., Jan. 2, the remaining debris is swept into the street and scooped up for collection before street sweepers make a final pass. Given the tremendous volume of trash that must be cleared in a short amount of time, none of the material is recycled.
Still, it’s better than cleaning up after the elephants.
