I will be doing a book signing here at the Sonoma State University bookstore later this month. I was looking through the astronomy section there, and what should I find but an astrology book!
Ironically, it was sitting next to the Cliff's Notes astronomy book, for which I was the technical editor, and Sten Odenwald's "Astronomy Cafe" book (Sten is an oldd friend of mine).
I mentioned this misplacement to the bookstore staff, and the offending material was immediately moved to the metaphysics section. Hurray!
