In Oklahoma, it's only trespassing if you've already been forbidden to enter. For example we had a neighbor that kept harassing our actives about noise (he lives a long ways away and 9/10 times we had nothing to do with the noise). He kept coming onto the property and letting himself in.

I had our house corp. president write a letter to him forbidding him to enter our property or we would have him charged with trespassing.

We haven't heard from him since then.. but we may next semester.
