Complicated park rules

Upon entering the children's park today, we were met with a set of rules.
Complicated rules.
To remember these rules it would take actual studying and memorization.

And then what if you were to apply them to something like this? Are there multilevels of rule in play? Who gets to use the whole of this jungle gym thing?

I thought it was helpful that this particular slide was clearly labeled. Shew, we don't have to go back an check the sign first to see if we can go down this one.

Apparently, these boys are too young for this A-to-B climbing thing, but are the mom's out of the age range to be able to help?

We didn't let the rules bother us--or maybe we're just rule breakers. :)
