If you come upon a cone that is not a pointer and you did not knock it down, you should stop at that cone (not the end of your run) and point it out to a courseworker and then after he acknowledges it go the most direct route, not through the course, to the finish line to get a re-run. Some clubs may not grant a re run for a misplaced cone so ask the specific rule for the club. I think VMSC does not give re runs for misplaced cones, but I am not 100% on that ask during the hour long driver's meetings.
