Even if you don’t always play by the rules, it’s worth knowing them just in case you get paired up with or against a stickler. But forget the old paper rule book and download the USGA Rules of Golf app. It’s free on iTunes, as is access to the Decisions On The Rules of Golf. Starting April 1st though the latter becomes an in-app purchase option. Best part of the app is that it’s searchable, so no more thumbing through mind-numbing verbiage to find what you need before you confirm a penalty. Just type in your rules situation and let the arguing begin (or end).
