Does your community sponsor a walk for Relay for Life, Making Strides Against Breast Cancer, or another organization? Many of these walks occur throughout the summer, and these events are always looking for volunteers. Organize young adults to volunteer at one of these events, whether helping to check people in, providing water, or helping in some other way. Consider bringing a tent or banner that has the logo of your church or young adult ministry on it so that, if people ask where you are from, you can talk about your group and what you do. This way you will not only be helping people and a great cause, but also spreading the word about your ministry.
