Hey, if you're checking in on Sunday, don't forget to pick up a copy of the Sunday Tribune; "Opus," the new Sunday-only strip by Berkeley Breathed, legendary creator of the much-missed "Bloom County" comic, starts today. The comic won't be on the Web anywhere, which means you're going to have to shell out the money for the paper to see it. Less heralded but also starting today is Darrin Bell's "Candorville."
