well the shrubs will take courage I guess and I wouldnt be surprised if they just shove them over so that they are in front of our garage or something. These are ppl who wouldn't scoop doggy doo a few inches on their side of the drive after a visitor to their place brought a dog that did it's business there.
I fear it will just escalate the issue as opposed to a fence, which we will inform them will be the outcome if the behaviour persists. I can't endure another yelling lol! I may just burst into tears
