Both Malls have indoor playgrounds that you can take the kiddies too. Whiteside Community center (and probably others)has a bikes and balls one morning a week. I try to host a playdate at my house once a month.
The only Mops program in this area is in Jenks or far east Tulsa. You can look them up on the internet.
There used to be a yahoo group that met regularly. I run one that has kinda died but I'm looking to get back to getting out at least every other week now. look for Metro Tulsa Moms and see if they are more active.
