Three explosions in two days but Joe thinks he's a lucky guy Two bombs exploded at the Boston Marathon moments after Joe Berti finished the race. Two days later, he was in his home state of Texas when he saw a fertiliser plant explode near Waco. "I was just like 'I can't believe this'," said Mr Berti, who had never witnessed an explosion before. Then he thought: "I just want to get out of here and get away from all these explosions." But Mr Berti is far from unlucky. In fact, he feels fortunate. He left both tragedies unscathed. Members of his running group and his wife were also unhurt. "It's a miracle," he told Associated Press. People keep saying, 'Don't you feel unlucky?' - Not only do I not feel unlucky, I feel blessed that my wife could be 10 yards from the explosion and not have a scratch. The bombings in Boston, which happened about 10 seconds apart at the finish line of Monday's marathon, killed three people and left more than 180 wounded. In West, Texas, a fertiliser plant exploded on Wednesday, killing at least five people, injuring more than 160, and levelling residences and a school. Mr Berti's road to the Boston Marathon started when he decided to run with Champions4Children, a charity that helps children with rare or undiagnosed disorders. He was one of eight Austin-area entrants who ran with that group. Each ran for a sick child or "training partner," who tracked the runner's marathon progress from home. Over the last six kilometres, Mr Berti, 43, who wore bib No. 25472, felt his body shutting down, and his pace slowed. But he was running for his partner, Drew, and he vowed to finish. "I had just run to the finish line and ... [moments] later I heard the first explosion, and then turned and saw the smoke," he said. Then the second explosion occurred and I saw a wave of people running. At that point, he said, he was so exhausted he could not run any more. He worried about getting caught in a stampede. He was concerned about members of his group who were behind him. He also thought about his wife, whom he was unable to reach. He told himself she was fine, because she was supposed to be at a restaurant. As it turns out, Amy Berti and a friend were just yards from the first explosion. She had just taken a picture of Joe, and was heading to the finish line to find him when the bomb went off. She and her friend were hit by shrapnel. Ms Berti was uninjured, her friend was bruised. But a woman next to Ms Berti had her leg torn off from the knee down, and lost all the fingers on her left hand. The Bertis left Boston on Tuesday morning and returned to Austin, with every hope of getting back to life as normal with their two girls, aged eight and 11. Mr Berti went back to work. On Wednesday, he had a day-long meeting in Dallas, followed by a museum tour. He was heading home on Interstate 35 and nearing Waco on Wednesday night when he saw black smoke up ahead. As he drove closer, he saw - and felt - his third explosion in two days. "You've got to be kidding," he remembers thinking. He described the giant fireball as a massive force that shook his car. He said it looked like pictures of nuclear explosions he had seen on television. As smoke billowed over the highway in front of him, Mr Berti held his breath and drove through it. After a few attempts, he was able to reach his wife - sparing her another round of worry.
