This “Light It Up Blue” awareness day display outside of the Airmen Family Readiness Center on Grand Forks Air Force Base, N.D., serves to shine a light on autism. Last year, more than 70,000 people pledged to “Light It Up Blue.” Whether it’s your front porch or your office; the whole world is going blue to increase awareness about autism, according to base officials.
