4 kids that live on that back of me have started to jump over my garden fence and next doors to get balls back. I have just watched them on next doors garden (getting a ball) but one them thought it was okay to have a bounce on the trampoline before going back. One boy kept throwing it over just so the other boy had to get it. Another thing the mother of kids has moved the trampoline right up to the fence so they sit on it staring in everyone's garden. What can I do? I'm dreading the school holidays. Tia
