I bought a membership to the Point Defiance Zoo & Aquarium this spring and it has been well worth the investment. We go about once a month and every time we have fun and get to see something new and exciting.
Earlier this week the girls and I decided to go and it was the perfect day. When we got there at opening time (9:30 am) there was literally only one other car there. The zoo was empty and the animals were active. We also got to get up close to the walruses who were being fed and cleaned (teeth brushed, etc.). There is one particular female walrus who is trained to do all sorts of tricks that we got to witness. Let's see, she nods yes and no, she waves, she rolls over, she gets in the water with a big splash (which we got a little wet from) or she can get in the water very calmly without any splash at all, she makes funny noises and does many more tricks that I don't know how to title. Pear loved every minute of it.
As usual, we left in the morning and were home in time for lunch. I hope to continue taking trips to the zoo as it's fun and educational. If your kids enjoy animals and you live within a reasonable distance from the zoo, I would encourage you to get a membership and become a regular. It's quite fun.
