Also known as "Big Mac".

The first women and science fiction panel was held at Big Mac in 1976.

Jeanne Gomoll described the panel thusly:

In 1976, Big Mac's programming included the first women and science fiction panel. We 
have Susan Wood to thank because she fought for it against vociferous convention 
committee opposition. We listened in the standing-room-only audience in spite of the 
heckling by men who thought the whole thing was a bore. (Some of them still think it is 
a bore, apparently, although their heckling technique has evolved since then.) We kept 
talking after the panel had ended in a packed, standing-room-only lounge for several 
hours afterward. It was an exhilarating, exciting, unbelievable gathering of people, 
overjoyed to have found one another. None of us used the word "boring" to describe 
the experience.
