This has not been a good year for me as far as attending cons goes. I was snubbed by quite a few of them. I only ended up with two--Wild Wild West Con back in March and Mile Hi Con, which comes up later this month. I'm not sure what's behind my waning popularity. And that certainly does not bode well for next year.
It's not all that clear attending these things does that much as far as promoting me the writer or selling my books. Yes, I always sell a few books--but never enough to defray the costs involved.
Mile Hi Con is one con I've attended for many years. I have friends I can catch up with and can usually find something interesting to do there. So, I'll go to Denver and try and figure out if I can find friendlier territory next year.
On a related note, sales of my books have fallen sharply. Alas, I don't have anything new out this year. The anthology I edited never came out and I haven't got any stories in any anthologies or magazines at all this year.
Maybe next year will be a little better. I just signed a contract for a new novella that will [hopefully] come put early next year. It's my fist sale in quite a while.
