I am sorry not to have posted this yesterday. I am down in DC at my publisher’s command, to join a panel at the AAAS conference at the Marriott Wardman Park Hotel, around noon. I don’t think you have to be a AAAS member to attend. We are panelling about writing science books, presenting science to the public, etc. etc. Be glad to meet any NRO readers, though I have to run for a train after the meeting & can’t stop for drinks, dinner, etc.
