Got word from a normally very, very reliable person that there will be a celebration for 60 years NATO in the Baden area. Though the date will be around 31-03 / 01-04 (yes I know this sounds as a joke.... but still.....)
At least something to keep in mind. By that time there will be notams to confirm I hope.
Edit: would make sense, cause after little googleling I found out NATO was formed 04-04-1949 so indeed that week 60 years ago..... but still find it tricky
