I live at the end of a dead-end street. About 6 years ago, after Hurricane Ivan hit us on the AL-FL coast, we had people up in our driveway and yard just sightseeing (or casing the place). After some A--bag decided that our front yard would make a nice place to spin out in (I mean tires spinning and mud and smoke flying!!!), my DH put up a sign at the entrance of our driveway. It is a regular street Stop sign and a No Tresspass, No Solicitation sign he got from work. It works for the most part, but occasionally we still have some hardy souls that want to "invite" us to their church.
