You can remove and add a new location to your application by using the City Manager window. You can find it under Cities menu in the main menubar of the program. After you opened the manager, select your current location (Muskegon) and press the Delete button. It will be removed and you can add a new one by pressing the Add U.S button for a location in United States or Add Int. for an international location.
