Treasure!

Another treasure uncovered today at the library coffee shop where they give away free books. No, not the self-published hardcover THE TRIVIALIZATION OF THE UNITED PRESBYTERIAN CHURCH, although that one looked like a real corker and I'll probably regret passing it by. The one I picked up today was a little 1967 mass-market paperback entitled LETTERS TO THE AIR FORCE ON UFOS. I really want to know what crazy genius is behind this selection of free books.
