They say the couple that plays together, stays together.
In the case of Southland couple Brett and Lisa Heslip, their shared hobby is of the very noisy kind; they are enthusiasts of tractor pull, a phenomenally loud and curiously fascinating combination of sheer grunt and horsepower.
Tractor pull involves four different classes of tractor: standard, pre 85, sport and modified. Participants compete to see how far they can drag the Tractor Pull New Zealand weight transfer sled.
It was easy to find the tractor pull area at the Southern Field Days at Waimumu on Friday, as it just required following the noise.
Mr and Mrs Heslip were both in action — Mr Heslip aboard Moonshine Runner, a methanol-powered machine that he imported from the United States four years ago, and his wife on Mitsin Bits.
