The rules are there to make it fair for everybody. I might also point out that they are written down. Familiarizing yourself with them would be to your benefit, so you understand the difference between a rules [insert pejorative term here], who is trying to pull gamesmanship B.S. and someone who is just following the rules, you know, to make it fair for everybody.
And I know even the latter group perhaps sucks the fun out of it for some disc golfers. Believe me, this game is very accommodating if you don't care for rules. That accommodation shouldn't occur in a sanctioned tournament though.
Great post.
To the bolded point, I want to point out that by the same token, the folks who don't care about rules can do their own share of sucking the fun out of things too. Lest anyone think you only can have fun by being lax about rules.
