When it comes to the festival, Frissen, who works full-time in the fishery – not coincidentally one of the largest industries in the city of Katwijk, where Haringrock is held – cannot stop talking about it. “I can go on like this for days,” he says. It shows the intense commitment he has for this festival, which is organised together with the city’s Vrijmarkt, that attracts about 40,000 visitors each year. Next to this, Frissen has set up the Ondernemersplein (‘Entrepreneur Square’), to give local entrepreneurs the opportunity to make a name for themselves. “I think it is important to mention that I am unable to organise this festival all by myself,” he says.
