Richard Rosetter stood inside his 28-foot grain bin and smashed a shovel into the thick layer of ice that covered his corn.
He was in a foul mood. His wife and a neighbor were pestering him, upset that he was working by himself, with no spotter to rescue him if he got trapped.
He had been doing this for 50 years, Rosetter reminded them that cold day in February 2014.
Just before 3 p.m. he realized his mistake. As the corn turned to quicksand beneath Rosetter's feet, he pulled out his cellphone to call for help. But the walls of the bin were too thick. The phone didn't work.
It took rescuers six hours to find his body at the bottom of the bin.
"I think it was totally preventable," said Gene Stengel, a local farm bureau leader who was hired to haul Rosetter's corn that day. "I tear myself up. What could I have done differently?"
At nearly all workplaces in America today, regulators, insurers and workers themselves demand safeguards to make it less likely for a careless mistake to become a tragedy. Coal mines, factories and construction sites are safer as a result.
Not the family farm. Minnesota and other Midwestern states allow small farmers to rely on their own judgment and experience to decide what's safe and what isn't. State and federal budget cuts have slashed farm training and safety programs, even as farm machines have become more powerful and more dangerous.
