T.M.
I found a lot of playgroups on a website called meetup.com. If you put in your zip code and what type of group you are interested in it will find them for you. When you find the type of group you are looking for you just need to send an email to the organizer with a little bit of info about yourself and if they have room they will email you a response. I have made many of new friends not associated with my husband and my son has gotten a lot of new playmates. Plus it gets me out of the house as I am also a stay at home mom.
