This is your government at work
Go to the FEMA page on Hurricane Katrina. Scroll down to the heading "Donations." After a warning about fraud and tax-deductability, there is an alphabetical list of organizations through which you can donate cash and/or volunteer. A few groups have been pulled out the alphabet and placed at the top of the list. They are: the American Red Cross and Operation Blessing.
We all know who the American Red Cross is but who is Operation Blessing? Take a big breath; you'll need it to scream. Operation Blessing is Pat Robertson.
Just for the record, most of the recommended charities are religion based.
