For manga/comic and anime/cartoon (They're the same fucking thing, with one just being from Japan) conventions, [color]red]no[/color]. Even if there was a convention right outside my house, I wouldn't go do to the likelihood of running into a group of those idiots who wear the Naruto handbands. And Naruto cosplayers, but they at least do more than a stupid headband.
The only convention I would ever go to is a gaming one, and even then, only PAX.
