Yeah, savingdogs, he was vulgar in person. I and another bookseller/fan were standing near his booth, all but genuflecting at being in his presence. We began a brief conversation with him, during which he managed to drop several f-bombs and a few other choice words just casually and without thought. He was wearing a pair of white double knit shorts that had several stains on them. His shirt was not fresh and he had a 3-day growth of beard and dirty hair. Ick. I had previously had a mental image of him as this brilliant, suave freethinker. So much for mental images.
