These are probably just examples but I'm firmly in the no-HOA crowd. If my home owning neighbor with a yard wants to park a truck in their yard I really don't care, and I abhor any organization that punishes someone for that. They could have a perfectly good reason to park it there. I've had former neighbors yell at me for fixing my car in my own driveway which makes no sense whatsoever except perhaps to privileged elitists with no DIY skills.
