"We are the face of rodeo, so you always want to be representing yourself in the best way possible," said Shiner.
"I don't believe it exploits women. There's more behind it than a pretty face -- we have to be well spoken, knowledgeable, and it's a great way to further our education and career."
For radiology student Shiner, winning the crown was a childhood dream come true, but also the beginning of a yearlong commitment involving up to 200 appearances across the country.
She'll return to university next year with $22,500 in scholarship prize money, and plans to pursue a degree in business and marketing.
It can be hard spending so much time on the road away from family and friends. But Shiner also takes her job as role model to younger girls very seriously.
"Miss Rodeo America was formed as a way to bring a little bit of beauty and grace to a sport known for its roughness and rowdiness," she says, adding: "But you still have to be prepared to get dirt in your nails."
