MIDSOMMAR in Vienna

Hi there all friends of Aqua vitae and herring.

Are there any more or less organized celebrations taking place??
If not, we could pick a location, and invite to an B.Y.O. aka "knytkalas". (it has nothing to do with celebrating Knut.. famous from the IKEA ads)
That means that you have to bring you own food and beverages..
Friday 24:th of June is the date, but I think more people would show up on Sat 25:th.
