From a dealer's perspective or from a collector's perspective?
From a volunteer's perspective?
From the amount of "stuff" one sold; or from the amount of "stuff" one purchased?
From previous attendance comparisons?
From the number of dealer tables?
From the scope of activities/programs offered?
From the entertainment offered in Las Vegas?
From the number of trades made?
From the number of new friends made and time spent with old friends?
From the value of the convention being held at South Point?
From the amount of money one came home with?
From the opportunity of picking up that scarce to rare item at a dealer's table, or purchases from the auction?
