T-shirts of *many* colors dot Ironman Kona every year. It takes over 5,000 volunteers doing all sorts of
jobs to make the race a reality. Each different type of job has its own color t-shirt. Mine for the
day was lime green. Security volunteers were red. Swim transition folks were in yellow. This guy
was working at a run course aid station. But there were many others! Each shirt becomes a valued souvenir.
