Hi! I live in Flinstone so just down/up from you. There are a number of MDC mamas in the area. We get together occasionally and have had API group meetings, although those are on hiatus right now. There's a yahoo group, apiofgreaterchattanooga, if you want to "meet up" with some other AP mamas around here.
I live just up the road from Rachel in Flintstone. I'm always up for park days or visits to the zoo (we have a membership) and the aquarium (our membership expires at the end of October, but I can get 1 adult and 2 children in on it if you want to meet there some time!). DS is 27 months old and is a bit shy around other kids, but he usually warms up fairly quickly.
