Appearing in St. Louis

I'll be in St. Louis, Missouri the first week of May on a whirlwind tour of four events on three days. I'll be selling and signing my books at all three venues. And all do ask for small donations.
(1) First is a debate in the Responsible Public Debate series held by the Ethical Society of St. Louis (which I hear is the largest ethical society in the nation) on Tuesday, May 3, from 7pm to 9pm.
