The yearly YWPDK ”julehygge” to place simultaneously in Aarhus, Odense and Copenhagen with more than 60 participants. Our regional representatives had arranged the Christmas events in collaboration with our local host. A great thanks to Rambøll in Aarhus, Sweco in Odense and COWI in Copenhagen for hosting the events, and contributing to the technical presentations. We will hopefully see you all again next year. Merry christmas!
