Visited here recently after driving by it for years. Wish I had gone sooner. It was a great experience, but really better understood by older children. The kids loved panning for "gold", and being able to purchase a "special" rock in the gift shop. The underground train ride was a great experience, except for the drill noise - could have done withut that, and it made the younger kids in the crowd cry. But overall, a pretty good visit. The only drawback is that it is NOT handicapped accessible.
