For 60 years, conventions – the Dum-Dums and Edgar Rice Burroughs Chain of Friendship Gatherings
– have been held throughout the United States, and even in Canada and England .
The majority have been held in four areas
– Kentucky, California, Maryland/D.C. and Illinois - and tied to groups located there -
the SubERBS, Panthans and Muckers, and the ERB Collection at the University of Louisville.

While has a timeline of conventions from 1960 to Present and reports of those following,
I thought it was time to take a look at where those conventions have been held, state by state.
Hopefully, this will help groups or persons thinking about hosting a convention and wondering if one was held in their state.

I divided the list into Dum-Dums held during science fiction Worldcons and Dum-Dums
that were held individually, then combined the totals. I also listed the ECOF gatherings by state.

I did not list any conventions that were announced then later cancelled.
No Dum-Dums were held from 1984-88, but informal gatherings were held.

Here are Dum-Dums held at Worldcons from 1961 to 1989:
(Editor's Note: ERBzine's alternate listings for these early events are featured at: )

      California- 4                One each are: New York, Michigan,  Florida,
      Illinois-      3                Arizona, Kentucky, Colorado and Georgia.
