Have you ever visited their blog? This is an awesome site. First, you can keep up and read summaries of the AAC events. Second, you can access the AAC blog "Inclined," or you can access "AAJ Briefs," as well as a host of other mountain related blogs. Third, you can access the link to iTunes where you can watch videotapes of the speaker series held in Denver. (I am in Chicago waiting for my connecting flight and am listening to Tom Hornbein talking about his West Ridge of Everest climb.)
