I could tell you that the reason is because Hollywood has co-opted the event into a medium in which Twilight characters get more media attention than comic book legends but the truth is that California is on the whole other side of the country!
We’re going to remain here on the East Coast and keep gearing up for the NY Comic Con in October. It’s got twice the comic book fun and none of the airport security.
On a related note, I noticed today that if you isolate the eye from the comic con logo, copy it, paste it together as a mirror image and then flip the whole thing upside down it looks like a close up shot of a cartoon baby bird.
So there you go.
