This included that most British (at least Scottish) of games; golf. To that end, at least one golf course near London wrote a special set of local rules to deal with the various hazards and distractions to the players caused by being at war while trying to get in a quick nine holes after work.
1 – Players are asked to collect the bomb and shrapnel splinters to prevent their causing damage to the mowing machines.
2- In competition, during gunfire or while bombs are falling, players may take shelter without penalty for ceasing play.
3 – The positions of known delayed-actions bombs are marked by red flags at a reasonable by not guaranteed safe distance there from.
4 – Shrapnel and/or bomb splinters on the fairways or in bunkers within a club’s length of a ball may be moved without penalty, and no penalty shall be incurred if a ball is thereby caused to be moved accidentally.
5 – A ball moved by enemy action may be replaced, or if lost or destroyed, a ball may be dropped without penalty, not nearer the hole.
6 – A ball lying in a crater may be lifted and dropped not nearer the hole, preserving the line to the hole, without penalty.
7 – A player whose stroke is affected by the simultaneous explosion of a bomb may play another ball under penalty of one stroke.
