If you'd like to read about science fiction cons which have past (and maybe plan for next year!) this might be a good resource...
I was actually looking for Blars, who was the main 'keeper' of the sciffylist for many years and who seems to have gone over the rim (well, maybe i need to keep digging!).
Anyone know where Blars is? I did +blars +science fiction and came up with some interesting stuff, like the link I offered above.
Keep the faith!
