People keep asking Joe Berti if he feels unlucky.
A bomb exploded at the finish line of the Boston Marathon seconds after Berti finished the race. Two days later, he was in his home state of Texas when he saw a fertilizer plant explode near Waco.
"I was just like, 'I can't believe this!'" said Berti, who said he had never witnessed an explosion before. Then he thought: "I just want to get out of here and get away from all these explosions."
