Er, I don't think Mike meant anything by it. Switzerland IS far tidier than just about any other country I've seen (with a possible exception of Singapore). I didn't visit the Italian parts when I was there but it was very interesting taking a day-trip from Brig, Switzerland (mostly German-speaking I think) across the border to Domodossola, Italy. It was ASTONISHING how much dirtier the Italian town was, considering it's just over the border.
