Hey there
I had found a great group in my area through a site called meet ups. I looked for your zip code for meet ups in your area and there are people waiting for a group to be created. Here is the link for people waiting for a group for introverts.
I know it might not seem appealing but you could create a group on your own through the meet up site.
Here is the general link for all the groups in your area who meet. Maybe you could find a group that suits your fancy.
I hope you find something. Sometimes the answer is...to create the group yourself.
Thank you for your question and come back to tell us how things go.
