Bus drivers in Milwaukee have gone above and beyond, from befriending the homeless to helping a mom suffering a seizure. Their heroic deeds have won them huge recognition this year. "We're the eyes and ears of the city, we're ready to help when needed," one said. One bus driver, Diana Serrano, came to the rescue of a 2-year-old girl who had wandered away from home wearing just a diaper and T-shirt. Another was on her usual route when she spotted a 5-year-old boy standing on his own.
