When I was in Brcko a few weeks ago. I participated, along with a few friends in an interesting race. You had to follow instructions and run to different parts of the city. When you arrived 1 member of your team had to perform a task. After completing these 3 tasks you then raced to a finish line. There were staggered starts, so you had no idea until everyone had finished what the placings were. It was a lot of fun!
