Spoiling Switzerland.

Switzerland - mountains, lakes, picturesque countryside and Graffiti.
Alas, the blight is spreading. It is three years since our last visit, but in that time, the sprawl of Graffiti tags has spread. They seem to follow the railway lines. Graffiti is dense in the cities of Zurich, Geneva and Berne, but it also manages to spread alongside the tracks far out into the countryside. The mountain railways are not badly infected as yet.They soon will be. What is it that inspires these daubs? Artistic or ugly? I know which gets my vote.
