i find it stange how people bang on about golf being a game of integrity and honesty where you are fully prepared to trust a golfer to impose a penalty on himself for grounding a club in a hazard for example yet you cant trust the score he entered on the computer because the card wasn't signed or returned at a later time
I think on course integrity and the rules of golf to qualify and authenticate a card written out by your PP are 2 very different things!
