You can help. Here are some ideas:
• Offer to speak in a correctional setting.
• Volunteer to be a temporary contact upon an inmate’s release and take them to their first outside A.A. meeting.
• Provide the correctional facility, with their permission, with DVDs of A.A. material.
• Donate the price of a Big Book or a “Twelve and Twelve” to your local corrections committee, or provide back issues of Grapevine and A.A. Conference-approved literature.
• Correspond with an inmate through the Corrections Correspondence Service.
• Support corrections committees in your district, area or intergroup/central office.
• Participate in correctional facilities workshops.
