Game 260 | February 6, 1978 | Sid Hartman

Game 773 | May 12, 2011 | Wheelock Whitney, Sid Hartman, Tom Swain
Looking to long-time Dunker members for a program, Whitney, Swain and Hartman, on the 50th anniversary of the arrival of both the Minnesota Twins and Vikings, talked about how Minneapolis and Saint Paul worked together and independently to position this region for an expansion of major league sports. The program was so well attended and popular that members suggested looking internally for additional panel-type programs.

NOTE: Since 2000, Sid has joined Dave Mona and each December the two of them host an annual meeting that includes many of the leading sports figures in the area with a rapid-fire question-answer session.
