On a Saturday at the Pacific Science Center in Seattle, Wash., life-size robotic dinosaurs roar. A giant video monitor shows a person sneezing as a spray of mist shoots down from the ceiling. Nearby, naked mole rats scurry blindly through a maze of tunnels.
And since it's all mud and rain outside, the place is packed with curious children and adults trying to keep up with them.
Loud noises, bright lights, crowded spaces: This is exactly the situation Mike Hiner tries to avoid with his 20-year-old son Steven, who is autistic.
