I also attended Tom Bowden's course at the Objectivist conference in Telluride and agree with your comment that he was "exceptional in conveying the magnificence of law in human affairs".

Another highlight for me was Craig Biddle's course on "The Science of Selfishness" in which he demonstrated that the Objectivist ethics was indeed a science, based on facts not mysticism - specifically, the facts about human nature and what is required for human beings to flourish.
