Yup, "Country Cookin' at Lakeside" isn't registered with the state either, not now and not in the past 40 yrs or so.
It's too bad; you start a business (without registering with the state) and build up name recognition over a number of years and then somebody else who actually takes the time to register properly can get you to change your name because they took the time to do it right and register. Some people don't get it.
