That all changed Wednesday when she won the $250,000 prize.
"Joanie found out she was the winner in a slightly unusual way -- by certified mail," lotto officials said from their Facebook account. "She was still suspicious that the whole thing was a scam, so she was pleasantly surprised to walk into the Fort Collins claim center and find out she really was the big winner."
Wary of the publicity, she asked that lotto officials not show her face in the photo op from the big payout.
She acknowledged, however, that it will be difficult to remain anonymous given her hometown of Cowdrey, just south of the Wyoming border, has a population of just 27 people.
"So even though she hid her face for photos, she said, 'Everyone will know!'" lottery officials said.
The winner of the largest prize so far this year also tried to stay out of the limelight. Edwin Castro won the $2.04 billion Powerball jackpot this year from a ticket purchased at a Los Angeles gas station.
Castro asked not to appear publicly and wished to remain private but issued a statement through the California Lottery stating "the real winner" is the state's public school system as it will receive $156.3 million -- the most earned from a single jackpot -- from his win.
Joanie raises alpacas and officials said she'll likely buy more. She also hopes to establish a trust fund supported by the winnings.
