Start at Roaders World via Dingelsdorf-Stein am Rhein-Steckborn through the outback to St.Gallen Switzerland. Lunch at a country inn. Then on to Prinz, then to Hörbranz and from here along the Lake to Heiligenberg (Germany) and Salem, including a tour of the castle there.
A short hop and we are back at Roaders House.
