Nelson Story was already a wealthy man in 1866. He’d moved to Montana a few years earlier and found gold. He used some of the riches to start successful businesses. But the 1866 venture was a gamble—drive 1000 head of cattle more than 1500 miles, from Texas to Montana.
He and 25 drovers successfully finished the trip in December of that year. He sold some of the beef to miners (at a huge profit), then used the rest as the foundation for his own herd. It made him another fortune.
