Can't imagine who would do that, and when. They said it happened near the summit, where a lot of spectators were gathered. Did no one see tacks on the road before the caravan arrived, or were the tacks thrown just as they arrived and no one saw it happen?
Aside from those questions in my mind, it was interesting to watch the sportsmanship play out.
