Buddhist Meditation Groups
You will find a number of Buddhist Spiritual Centers in your local community by looking through the phone book or local activities Calendar. I have found that they regularly hold meditation groups and classes. These may not be focused on 11th Step Meditation, but they will be supportive to your spiritual path and will provide good teachings and concepts on meditation.
Here is a website that lists many other Buddhist websites. The may be helpful to you in locating local meditation groups in your area.
