Updates: I got 'em!
I may or may not do my announcement system. We'll see. Either way, I did build emergency exits. Seeing as how this involved tearing down sections of the fence, I decided to re-do the entire fence system. I thought it looked weird in the first place.
Okay, original fence.

Aaaand the new one.

As you can see, it's much taller and more solid. You can also kind of see one of the emergency exits (there are three, the other two are by the jail and between the garage and meeting hall)
