Once you’ve scanned James Hay’s San Diego Fandom Index you’ll believe his hometown must be the center of the science fiction universe.
Since Hay took over editorship of the site he has expanded its coverage, and started posting info about cons, meetings and events occurring farther in the future than before.
And Hay has also revived his California Convention list, plus a separate list Ren Faires and Reenactment Events.
Update 01/25/2015: Corrected California Convention URL per comment.
The California Convention List link leads to a 404 Not Found reply.
Thanks Fred — fixed now.
