This is a good deal if you have kids and live in the Portland Oregon area.
It's a fun thing to do on some of those rainy winter days. Even if you don't
live in the area there is a long list of other science museums that offer
reciprocal privileges. So you can probably use this membership to get into
your local museum as well.
