Great children's museum with a amazing (20,000 sq ft!) outdoor play area which includes a multistory maze/slides tower. When driving along I-5, it is well worth the stop even though it is close to Portland (take Hwy 22 off I-5 to Salem's riverfront). Also has reciprocal benefits with other science/technology museums. Pack a lunch which you can eat in the picnic area (food offerings are limited to hot dogs/ice cream/snacks).
