One lucky person won the $1.3 billion lotto jackpot at a gas station outside Chicago. The Speedway gas station is in Des Plaines, Illinois, located right near the O'Hare International Airport. The fact that the gas station is located so close to the airport means the winner could come from anywhere. Experts say the first thing you should do if you win the lottery is to take a selfie with your ticket to have evidence that you won.
