A day after my Riverside appearance I'll also be speaking to the Orange County Backyard Skeptics in Villa Park, California (at 7pm, Thursday, April 14). To attend (and get the venue address--it's held literally in a member's private but lovely backyard) you must be a member of their meetup group (which you can join here), or personally invited by a member. Suggested donation is $5 (or $10 if you'll be enjoying food provided during the event). I'll be selling and signing my books as usual. The topic will be "How Christianity Began Is Proof Enough It's Bunk," in which I'll discuss some of the essential features of how and when the Christian religion began and why it looks exactly like just another religious cult of its time and place, and not at all like the idea of a universal god.
