Yeah, I got dinged coming down from Grindelwald, 29 in a 25 at one of those "instant construction zones". They give you 3 km's of grace, so I was hit for 50 sfr's for 2/3's of a mph over. Reminds me that I still have to pay that one...
Harder to forget about this heading into Switzerland, where they practically pull you out of the car when you reach the border. Austrians are waaaay more laid back.
