CJ's bus is on the east side of Indianapolis, caring for kids affected by this week's tornadoes. Volunteers left Evansville Thursday night. CJ's bus is a mobile recreation unit established by Kathryn Martin. Martin named the bus in honor of her 2 year old son, CJ, who died in the November 2005 tornado. The bus goes to disaster areas to help families, particularly children, cope in the aftermath of tragedy. It offers lots of activities like arts and crafts to keep kids busy in a safe environment. The bus is staffed by Martin and other certified disaster relief responders. They say they'll stay in the area until their help is no longer needed.
