A "charity" not filing it's tax exempt status papers is like a truck driver "forgetting" to renew his license.
C'mon Imus, the charity scam is so easy it's the tool of choice for dimmwitted libs all over the country. It's just a piece of paper for christsake !
I'll add a negative observation. Although it seems poorer kids go too, if you listen to Imus you know this ranch seems to enroll sick children from among the richest and most powerful parents in the USA. Imus plainly uses the ranch, and his contacts with prestige doctors, to cultivate his personal relationship with the rich and powerful.
