Keep Sedona Beautiful Dark-Sky Committee and Big Park/Village of Oak Creek Dark-Sky Committee are joining Red Rock State Park to celebrate Earth Day. Dark-sky information will be available, plus examples of good outdoor lighting fixtures. Learn how we can reduce light pollution by using light only where needed, when needed, and no brighter than needed; by preventing light trespass to the sky, to neighboring properties, and to areas not requiring lighting; and to use amber LEDs, not white. What a day to celebrate our magnificent night sky!
