LAS VEGAS– In a usually unused and forgotten Las Vegas neighborhood, hundreds of people gathered and made it a vibrant green community, if only for one weekend. The Build A Greener Block project took a small portion of Main Street and, instead of shutting the entire street down, narrowed the street to showcase how everything can work together. Pedestrians can walk, bicyclists can use their lane, and drivers can still parallel park their cars. (Photo by Erika F. Washington)
