Another "ah hah" moment for me that seems so simple.......but trips up a lot of people trying to 2d guess the rules and find obscure situations that seem to be in conflict with the rules.
From section 17, in discussing the Committee's responsibility to adopt Local Rules as appropriate:
It is therefore a principle that the Rules should not attempt to cope with the exceptional. To do so would simply throw all normal play out of balance.
and, in discussing improper Local Rules, specifically giving examples that include "Lost Ball, drop in fairway, two strokes." and "Ball within two club lengths of rain shelter, drop away, without penalty.".........
The use of Local Rules is often essential to the proper playing of the game, but they must be in conformity, and not in conflict, with the Rules of Golf.
