Adoption Support Groups??

Hi, I was wondering if anyone had any information about any adoption support groups in the area of- King of Prussia to Reading? My neighbors adopted internationally, and the agency they went with in PA is great. They meet regularly, they have outings, parties for the children and parents, all related to adoptions from China. I went domestic, with an agency in CA. I have had no contact with them since the first few initial calls that my daughter was born. I am also a single parent, and have checked the web and phone book seeking groups of other folks who have adopted in the area - no luck ! If anyone has any information, I would appreciate it. Thanks moms and dads !
