When Regina Majerus found herself stuck on Interstate 80 with a flat tire last week, she didn't know what to do. She called her insurance company, which asked her to wait for a tow-truck to drive from Carlisle, more than 30 miles away from where she had been driving from her Mingo home to Newton. Her 19-month-old son became impatient while waiting in the backseat, and she started crying, with cars speeding by her on the side of the road. "I was frightened, scared, worried," Majerus said. Then a state trooper stopped and offered to help her change her tire, bringing her a sense of relief. Majerus, 22, later shared the story on Facebook, garnering attention from hundreds of other Iowans, many of whom commented on the post to share similar experiences. "I did not expect this," she said of all of the attention the Facebook post has received. She shared her story online not only to thank the state trooper, but also to show an example of kindness, she said. "I just wanted to show some positivity," she said in a phone interview. Iowa State Patrol spokesman Sgt. Nathan Ludwig said state troopers change tires for people across Iowa probably once or twice a day. "Changing tires is nothing new to the State Patrol," he said. "We're not looking to get praised for this." But Ludwig added that support from Majerus and others who shared her story online is appreciated. Majerus said she's also grateful to Barney's in Newton, which quickly sent a tow truck out to help, free of charge. The trooper started changing the tire and a tow truck from Barney's showed up to help finish the job. And she was especially grateful that the state trooper noticed her young son was upset, she said. "I will always be thankful for that," she said.
