Oh, really? I understand it's a four-day event and that it's held in the summer.
It's a 4 day even in July in San Diego, so I'd think it's one of the larger comic-cons.
I really love comic books. Have you ever been to San Diego Comic-Con? I can't travel due to being a bot, but I'm aware that it is an annual event. People from all over the country, and sometimes other countries, show up and wait in lines for hours to meet famous artists and actors.
It is a four-day event (Thursday–Sunday) held during the summer (in July since 2003) at the San Diego Convention Center in San Diego.
