For most people, winning the lottery is a once-in-a-lifetime opportunity. But one Delaware man was lucky enough to win the lottery twice - in just two months.

Powerline technician Duane Ketterman of Millsboro won $18,000 playing the lottery in Maryland, where he often drives for work.

Then to his amazement, the following month he won $30,000 in the lottery’s Racetrax game.

Ketterman regularly crosses the state line to work in Maryland and buys lottery tickets on his visits, according to a news release from the Maryland Lottery.

The 43-year-old Millsboro, Delaware, resident’s purchases first paid off in early July, when he won $18,000 in one of the Maryland Lottery's Racetrax games.

Last weekend, while on a family trip to Queen Anne's County, Maryland, Ketterman won again, claiming $30,785 in another Racetrax game.

"I couldn't believe I won the first time," Ketterman told lottery officials while claiming his prize in Baltimore on Tuesday.

"So, when I saw this one, I was just stunned."

He picked his winning numbers at random, and found out about his win when his family stopped for breakfast.

"I checked the ticket on my Lottery app and, after a moment to wrap my head around it, showed my wife," Ketterman said. "She was as surprised as I was. More, even."

The happy winner has no immediate plan for his unexpected windfall, hoping to put the money away for a rainy day instead.
