so, while my wife was home alone this morning, she saw someone scale our fence and come into the backyard. she decided to confront him (i told her already that was the wrong decision, but she said she would rather do that outside than inside the house), and he told her some b.s. about looking for a basketball that had come into the yard. the gate was locked and we have an 8-ft. wooden fence, but that obviously didn't stop him from deciding he could trespass into our back yard. anyone have any tips about preventing this kind of behavior in the future?
