I agree with tx, allowing this perv to continue because of what he may or may not do next is the wrong approach.
You can control what you do about a situation, not what someone else does.
And why should you have the expense of putting up a new fence ?
He should have to flip the bill for it since it is his actions that require the need for it.
A repeat of what others have already said, start the ball rolling by making a phone call to your local PD.
Then get a hold of a lawyer to file a law suit.
If there was a guy like that around here, I would be absolutely pissed to find out others had seen this and not reported it.
Being a woman myself I cannot understand why your wife would put up with it for a second.
