Technically, I know, when I say words like "stock" and "stalk," they sound the same, but I picture them as slightly different in my head, and in my mouth-shape. If I answer that way, though, it claims I have a midland accent, which I don't. So if I go with how I know they actually come out of my mouth, then it properly places me as west-coast.
