PDGA Rule Book
This book is actually blank, You can write in whatever rules you want and then you will be right.
But in all seriousness this is the current, official copy of the PDGA rules.
Yes they are confusing, yes some of them are ridiculous, superfluous, hilarious, ludicrous, outrageous, preposterous even. But they are the official rules and if you are playing in a tournament people will penalize you for breaking them.
But the real question is, When you read the word penalize, how did you pronounce it in your head?
