Now in its sixth year, the Day on the Green at Montgomery Village is back to promote green businesses, inspire environmental awareness and to party with music, art and innovative demonstrations. Get a look at some electric cars, groove to the sounds of Shana Morrison and her band Caledonia, and bring the kids for crafts and educational activities. All proceeds from the event are going straight to environmental advocates Southeast Greenway Campaign, the Sierra Club and LandPaths. The party gets started on Saturday, April 25, in Village Court at Montgomery Village Shopping Center, Santa Rosa. 1pm to 4pm. Free.
