Local moms get togethers?

I'd like to start some sort of playdate group with those of you who are in the Olympia area. I know there are a few of us! It'd be fun to hang out once a month or so. Have girlfriend time, let the kids hang out and play, and get to catch up on old times! What do you think? Where could we meet when it's cold and yucky? In the summers I'd love to visit different parks and meet up with you guys! How many of us are there who are local, anyway? Anyway, let me know if you're interested in setting something up!
