Hannah Simpson, of Southland, New Zealand, rides a 7-year-old dairy cow most days. It started when her parents said she wasn't allowed to have a horse, the then-11-year-old got creative. Now she and Lilac race across fields and master jumps, as documented on Simpson's Instagram page. Simpson, who works at a dairy farm, says she's tried to ride other cows but has only had one other that could jump. While Simpson admits she was a particularly adventurous kid when she started, she wouldn't necessarily advise other people to try riding cows.
