Baden ist Spitze. Der Besuch der Baldegg für viele Besucher spannend. Der Weg dorthin ist gefährlich. Die Strasse ist eng und der ö.V. fährt mit dicken Bussen. Die Ränder der Strasse sind mit scharfkantigen Steinen versehen. Ausweichen ist gefährlich ( der Schreibende hat selber schon einen Pneu verschnitten). Man könnte allen das Fahren erleichtern, wenn man die scharfen Kanten brechen würde. So könnte man besser ausweichen. Irland macht das vor. Mit freundlichen Grüßen Franz Stadelmann, Baden
