DR DtM - Hair In a Can is still available. Years ago when there was still some foliage on the top of the mountain, I bought a can. It was icky and unsatisfactory. But everyone should try it once, just so you know.
Ayn seems to capture her most fervent converts in their late teens and early twenties, and then as we grow older we are a bit selective about which of her ideas we embrace. But I still enjoy the sweep and scope and suspense of ATLAS SHRUGGED.
Years ago when Ayn was on The Phil Donahue Show, some of the audience were rabid accolytes, some had never heard of her, and some said they were an author of their youth. One woman was only slightly critical and Ayn cut her off sharply:
"If you don't like my books, what are you doing on my show? I wish I could take back all of my books from people like you, you don't deserve to own them. Write me a letter." LOL....she was a great interview. I was always hoping that Tom the late night NBC guy or Mike Wallace would have Ayn Rand and Harlan Ellison on the same program!
