it's not a 'rule'...it's a law. and I've been wearing seat belts since before it was a law. but i can be fined and, at least temporarily, lose my freedom for not wearing my seat belt. not the same as a rule. and even though i wear my seat belts religiously i oppose the law mandating it just as i oppose the law requiring biker helmets.
But the principle remains the same. It's a rule because they can't make it a law. This is such a stupid issue to be arguing over. Just go to a campground that has no rules or no rules you don't like and be done with it.
