If none exists, organize one. Meet periodically with other youth workers in your area to share ideas and problems. They can be a great resource for you. When a distraction occurs, acknowledge it. It's the best way to regain the attention of the group.
People can call anytime and get details for upcoming events and activities.
Parents especially will love this. If your group is small, meet in a small room. Always make sure your meeting place is casual and comfortable. It should include photos and articles about the past year's activities. It will be a positive reminder of the good times shared by the group.
