Actually, Imus as said recently that he can't breathe at the ranch - I guess the elevation is high. That would really impact on how much time he spends there.
I don't believe half the stuff he says. He is totally self-absorbed. It would be interesting to learn exactly how much time he spends at the ranch. Since it is a tax exempt operation, there are limits to how much time he can be there legally for tax purposes in much the same way a landlord is limited in spending time in his rental property. It affects depreciation and other deductions.
