As per http://www.pillowfightday.com/ a few people in Vienna just happened to meet up and who would have guessed it, a few of them just happened to have pillows along and thus Vienna was able to partake in this wonderful event too. A great spectacle of the many tourists who will now have one more good tale to tell about their visit to Vienna. more photos:
