I'll second the Mitch Vaughn recommendation......I only met him once three or four years ago -- at a meeting I set up with a third (who he already knew) at which they put on a show for me.....Mitch was/is a very smart, low-key, easy-going, and friendly guy.......may not be the utter model of alpha masculinity to some, but he was at once approachable, chatty, savvy, and kick-back......one of the good guys (at least as of three or four years ago!!)
