"Usually that meant passengers who had plenty of money gave nothing, while those who had nothing often gave something."
It wasn't until 1982 that Mr Burden formed the company that was to become a household name in Hawke's Bay.
Despite numerous offers to buy the business two decades ago, he decided to keep it in the family and sold it to nephew and Hastings district councillor Rod Heaps.
Four years ago Colin and Kim Lindsay bought the business, with the tractor and trailer now in its full-seasonal swing.
Once a single tractor business, the enterprise now boasted eight casual staff and five engines, with a maximum muster of 180 tourists per trip.
Neither Mr Burden nor Mr Heaps had put their cues in the rack.
"Rod still drives and I'm still an occasional driver," Mr Burden said. "It's great that I can still do that. It's been a very enjoyable business with lots of memories."
