On Saturday, April 13, from 9 a.m. to 2 p.m., Philadelphia residents can pick up a rake, paintbrush, or broom to participate in the city-wide 2013 Spring Cleanup. Volunteers will be bagging up trash, distributing recycling bins, and painting walls to help beautify places across the entire city. The 2008 effort was the largest one-day cleanup in American history, and in 2012, more than 12,100 volunteers collected more than 1 million pounds of trash at nearly 350 sites around the city. For more information on this year’s Spring Cleanup event, including volunteer information, go to www.philadelphiastreets.com.
