People how don't live in our neighborhood should not use our dog park and I am going to tell them that.
Why would you say that to them?
I've kind of grown tired of them.
They have just as much right being there. It's a public park and anyone can visit it.
They are annoying and this could teach them a lesson.
You don't have the right to tell people what public park they can use. If they annoy you then you can stay away.
