Yesterday fell snow in Vienna, today the sun was shining; a good reason
for making pics: but then a rescue helicopter flew in at Mariahilfer
G�rtel - a main road with, 4 lanes in each direction and in between some
free area and the tracks of the tram (close to Westbahnhof).
Pics are here see "Exkurs": http://public-transport.net/bim/TT09.htm
