A visitor code we can defend

A visitor code becomes trustworthy when readers can see the force behind each sentence. Must and must not express requirements, so a code should connect them to a responsible authority or a posted notice. A writer's preference is not enough. Should gives advice that can be supported by a reason: visitors should keep an appropriate distance because close movement may disturb wildlife. Can presents an option, such as using a marked refill point. These meanings should not be mixed simply to make a sentence sound stronger. A good code also respects people. Asking before taking a close portrait is a practical way to respect another person's choice. However, the writer should avoid inventing one rule for every place; actual policies may differ. Cause, result and concession clauses make the logic visible. Because introduces a reason, so points to a result, and although acknowledges a contrast. The final step is version control. Give the date of information that may change and direct visitors to the current notice. Responsible language does not weaken a code. It helps a visitor know what is required, what is advised and what remains a choice.
