Zoo Friends Membership a must
By A Yahoo! Contributor, 2/15/05
This isn't much of a value unless you buy an annual membership for the family. Before my kids were in school, we had friends who also had a membership, so we would go, literally every week. It was terrific, and we could enjoy as much as they wanted to each time we went, and we didn't feel like we had to cram it all in with one trip, every time.
