The man's resume speaks for itself, but my main thoughts for selecting Bob are as follows:
The man travels extensively, and has become the master of the online-offline;
He likes a variety of different wines and is the poster child for Malbec;
He posts numerous tasting notes;
He was a 6/15 attendee, and I had the pleasure of meeting him and his lovely wife;
Dr. T's description of him from an online-offline remains a classic in my mind.
Good Luck and Happy Hunting!
