The last thing Viola resident Darryl Collins thought about when he was fighting for his life two years ago was competing in a national sporting event.But that’s exactly what Collins did earlier this month when he participated in the Transplant Games of America in Houston, Texas. Collins was among 3,500 athletes from across the United States who competed in the Olympic-type event held every two years. It comes after he received a double lung transplant at Vanderbilt Medical Center on May 30, 2012.“It was a big step, but my recovery is not over,” said Collins of the Transplant Games.
