Every year we have HOLHOW, this stands for: The Very Long Ascension-day Outdoor Weekend (it makes more sense in dutch). Not only is this an awesome weekend, it is an extra long weekend. Starting on Thursday and ending on Sunday. Every year this weekend has a special theme and this year it is going to be all about sabotage >:D
The location is so secret that even we do not know it yet, the date will be from the 25th of may until the 28th. So reserve those dates in your agendas.
