“I don’t know how it happened, but it happened,” said Heather Cole.

Cole was driving her three kids to their dentist appointments in Mason City when they stopped for drinks at a gas station. That store was out of ice, so they made another stop at Coalville Stop-N-Shop, 23930 Boies St. That’s where Cole decided to buy a couple of “Silver Streak” scratch tickets.

“I had a $20 winner that I was cashing in and the lady at the gas station was like, ‘Do you want any more?’ I’m like, ‘Sure, give me two Silver Streak tickets,'” she said. “And lo and behold, I went to scratch it and revealed $100,000.”

Cole scratched her winning ticket in her vehicle outside the gas station and said she was almost in tears as she told her kids about her big win.

She claimed her prize Monday at the lottery’s Mason City regional office, and plans to use her winnings to pay off debt and take a family vacation this summer.

“I knew one day hopefully I would get it,” Cole said of her win. “Everybody wants that when they’re scratching tickets.”

Cole is the second person to claim a $100,000 top prize in Silver Streak, which was just released on May 6. It is a $10 scratch game with overall odds of 1 in 3.25.
