The Imus ranch is bogus
 

The Imus ranch is a brilliant scam. He persuaded a bunch of corporate
donors to build him a multi million dollar estate in New Mexico. Imus
uses the property as his private residence. Getting the project
classified as a charity makes everything tax free. The cancer kids are
only allowed on the ranch ten weeks per year, they cannot be
accompanied by their parents and they are not allowed to sleep over.
The dying tykes show up in the morning, muck out the stalls and leave
by nightfall. Imus created The Perfect Con.
