I remember a story my father told about coming home from the Korean War. He said that there was one charity set up selling donuts to the service men who were returning. The Red Cross was set up giving away donuts to the service men. That speaks volumes to me.
I am sure that there will be many local churches and charitable efforts organized to help victims of Hurricane Katrina. If you wish to help, please do so. One local church in Selma has helped with hurricane victims in the past by gathering clothes, bottled water, food, and other items for transport into the affected area.
If you wish to donate monetarily to an organization that will help, then I can recommend the American Red Cross with all confidence that you will not be "scammed". Click on the banner below to donate online, directly to the Red Cross.
