A little further on, between Olst and Boskamp, we came across a number of classic tractors. The proud owners call themselves the Trekkervrienden. Their motto? ‘Eem uutpuffn’. The four mates go on holiday every year with their motorised workhorses. “Driving these tractors is the best thing there is for us”, says Hennie Steerneman, one of the mates. “You do need earplugs, they make quite a bit of noise.”
