If you haven't already read it, John Rickards has an excellent post up about conventions, why writers go to them, what's the use, etc. that looks at the sales downside, the social upside, and the fun factor.
I know fear of crowds prevent some writers from attending cons. Anxious folks might try HypnosisDownloads.com's Overcoming Agoraphobia $9.95 hypnosis download. I don't see any downloads for conquering fear of over-perfumed ill-mannered women and balding married men reviewers on the make, but let me know if you find some. There's one for overcoming fear of unfamiliar surroundings that might also help. Is there anything stranger than a con? I mean, besides two cons?
I've been able to successfully dodge these things for years, but I may go to one in the not-too-distant future to see a dear friend. No, I'm not telling you which friend or what con. I'm actually hoping to make it a drive-by support thing -- get in, grab my friend and run out so fast the lobby revolving door blows off its axis. From there we can go have a nice quiet dinner and catch up. Then I can hit the local CDC, have the friend thoroughly decontaminated, draw bloodwork, etc.
I don't have to return the friend, now that I think about it. It's not kidnapping if you accidentally on purpose get lost driving back, right?
If I have to go in and register and stay as moral support . . . Lord, pal, I must really love you to even type those words. All right, I might still get away with it. No one should recognize me except the friend. I could register under one of my ten thousand pseudonyms; no one can keep track of all of them, not even me. First thing I throw away at a con is that dumbass name tag anyway.
Or I could pose as someone everyone would want to avoid. Like an IRS auditor. No, everyone will want to report whoever beat them out after the awards ceremony. Maybe an unpublished writer wearing her heroine's costumes and carrying around a 6-1/2 lb. copy of The Book of Her Heart printed in italic font on pastel pink paper because you know editors really don't like Courier on White but they never tell you that because it's an inside thing. All I'd have to do is make up a pseudonym that sounds like the brand name of an overnight feminine hygiene product. There's always so many of those gals, I could blend in easily -- but then again, period clothing makes me itch.
Who else do people want to avoid? Hmmmm. Is Margaret Atwood real tall or especially skinny?
