The Center for Inquiry will be holding a critical thinking meeting in New Orleans over Halloween. Called CSIcon (pronounced sigh-con, no relation to Maya's home planet), it's promising to be quite a fun skeptical meetup.
For a taste of what's to come, CFIer Adam Isaak made a promo video for it. You may recognize some of the folks in it.
Since it's over Halloween, you know there'll be silliness... and I hear there's a parade and costume party.
