(PORT HURON) -- Kelsey Zachow will never forget the heart-pounding adrenaline rush she felt when she learned she had won a $66 million Mega Millions jackpot. The 24-year old Port Huron woman won her jackpot last month on what many consider the unluckiest of days--Friday the 13. Zachow purchased five Mega Millions plays at Sonny's Mart, located at 12 Market Street in Mount Clemens, and her fifth number, an easy pick, matched the Mega Millions numbers drawn that evening. Zachow elected to receive her jackpot as a one-time lump sum cash payment of nearly $38 million and will take home nearly $27 million after taxes. Twenty Michigan ticket-buyers also won $500 in that lucky Friday the 13th drawing.
