Please excuse me for my newbe question, but I have not spent much time looking into the actuall enforcement of penalties untill just now. I am not finding anything that tells you when you apply half the distance to the goal. I am going to assume that it is once you can no longer apply the full yardage of a penalty? i.e. Illegal personal contact (0n B) at B's 10 yardline. at this point it would have to be placed at the 5? Thanks!

In NFHS, you enforce half the distance anytime the full penalty would be more than half the distance to the goalline from the point of enforcement -- in other words, inside the 30 on a 15 yard penalty, inside the 20 on a 10-yard penalty, and inside the 10 on a 5-yard penalty.
