Old lady complaining about my shed

i store my car and parts car at my fathers place. we had problems with the neighbors complaining about the cars. they called the cops on us. they told the cops we were street racing. they showed up and read us the riot act about what they could do. so for a week we would take our street cars out and stop in front of her place, pop the hood and rev the **** out of it. after that week her son stop my dad and asked us to stop and we did. now if we do a run down the road with the race car no cops are called. not quite the same but that is my story.
