You know I too have been there, and while you might not see anything wrong with a rusted out old car or two sitting around, it's pretty obvious that your neighbors do. Way to often, people think what they do on there own property is their problem only, but the truth is, your action, or lack there of, causes pain to other. A pain in the form of a Blithe, making the neighborhood look run down and trashy. While I think most times, the local governments try to stay out of the lives of the normal property owner, I have to agree, that this is one issue that causes a problem for enough fellow property owners that some times action is needed.
I know this is a Hot Rod forum, but much of what is refereed to as a Hot Rod here, is really just worn out junk, people are nursing along and using for daily transportation.
