Also, you can help us by sharing our social media posts with your friends and followers. We've already received an honorable mention in the "Pre-Dog" Social Media Challenge for this video tweet, which answered the question, "What does your organization do to make our region stronger?" and launched a Facebook contest to ask you to show your #CAPlantLove. Please help us spread the word and we hope to see your support on May 4!
