Peggie: I read the discussion about dumping porta potties in another forum and found it incomplete. Could you give your thoughts on this subject, especially from the point of view of interior lakes where either marinas don't exist, or where they lack dumping facilities for the public. Its not the sailboats that I worry for most on this subject but instead the more abundant small power boats. Would like someone to provide information to users and administering agencies of small lakes to better address this subject as now it is mostly hidden from public discussion and probably results in water pollution even of culinary water sources.
