From this story in the New York Times:
Every weekend, Michael Morris and his 2-year-old son, Jacob, visit this small town's enormous new $14 million fishing museum. They watch bream and bass swim in aquarium-size tanks. They play with an interactive model of a fishing boat and try to catch fish on a computer simulation using a rod and reel connected to a video screen. And because the museum, the Go Fish Georgia Educational Center, is primarily financed by the state, their father-and-son outings costs only $5.
