I hope they can structure his activities / presentations with a co-presenter who is adept at audience engagement, interview for substance, and general energy / enthusiasm. God bless him, but JB will not raise anyone's pulse rate all by his lonesome unless they are already well into mineral geology.

  I hope this has been considered - a co-presenter - energy, enthusiasm, sales oriented, and not a stranger to Geology, someone to take the focus off of JB long enough so that when the focus goes back on him, it is to answer the questions that have been laid out and partly answered in arriving at the question itself.  The Sage, dispensing to the seekers.
