Hi Alison (I'm assuming you're the Alison that I know from your profile!) I know this post is old and that you know about this already but since this is the first hit when I googled "Potsdam Playgroup" I thought I'd post the link to our yahoo group for anyone who is looking for a playgroup.

Hope to see you soon! Elena
