Playgroups in S Florida

Hi - My husband and I are moving from Minnesota to Florida this fall (next month or so) and I'm curious if anyone has playgroups with other children who are adopted. When I get down there, I'm interested in creating a support group either online or a playgroup if possible. My son is 4 1/2 years old, and an only child at this point. (hopefully we can adopt again.) Has anyone done a playgroup before? Thanks JAK
