Although I'm an opportunivore, choosing to eat whatever tasty foods come my way, regardless of animal content, I like to think I have some dietary standards.
A 10th Street resident came home to find a table smashed and computer stolen from his home. The windows had been left open, allowing free access for a malicious opportunivore.
Those were heady times for a young, omnivorous reporter: I handled everything from stakeouts to regional front-page features, writing on topics from nuclear power to heroin addiction. I call myself an "opportunivore" because I’m still drawn to a wide range of stories.
