Hi S.,
Welcome to the area! There are some great ways to meet other Moms in our neck of the woods. One way that I have found helpful is joining a MOPS group (Mothers of Preschoolers). You could go on their website and find a group that meets near you http://www.mops.org/
There is another online group that is local to our area called 24/7 Moms and you can find them at 247moms.com. It is a great way to find out information and there is a blog where you can "talk" with other Moms.
I have also found the YMCA to be a good place to meet people as well through my kids swimming lessons etc. Gig Harbor has a greta new Y and it isn't too far from you.
Hope these ideas are helpful and not ones you have thought of already.
Good luck!
A.
