One response to Hurricane Katrina was a very generous outpouring of concern and care by Americans throughout the country. Many of our contributions could be handled immediately only because a solid infrastructure of charities already existed. Our many charities are a tremendous source of strength of which we can and should be very proud. On a personal note, I have been involved with charities at almost every level: as a recipient, as a contributor, as a founder, and as a researcher who studies charitable giving and charitable organizations.
