In 2005, shortly after Hurricane Katrina struck the Gulf Coast, Neufeld spent three weeks as an American Red Cross volunteer in Biloxi, Mississippi. The blog he kept about that experience turned into a self-published book, "Katrina Came Calling" (2006). Later, Neufeld was asked to write the introduction to a book called "Signs of Life: Surviving Katrina", a collection of photos of the hand-made signs that appeared in New Orleans and along the Gulf Coast following Hurricane Katrina. Profits from sales of the book went two organizations still working in the area: Common Ground Relief and Hands On Network.
