My four (adult) friends and I visited the USS New Jersey in August of 2002. We, old dogs, learned something new at almost every turn. We ran, we jumped, we acted like children. We had more fun that the children we saw being pulled around by parents. This is a good way to spend an afternoon. Its a museum, but without the stuffiness of a museum!
Pros: outside activity, YOU can learn
Cons: climbing, slippery when wet
