Didn't notice them because I see them everyday.

Really? A clothes line and clothes pins?
When was the last time they were used.

Funny thing is, everyday I walk under these, as a matter of fact thinking about it just now, there is a mechanical clothesline system above where I am taking the photo from. Had I actually thought about what it was I would have removed it years ago, but since it never dawned on me it is still in place. As a matter of fact when I spray painted the kitchen cabinet doors, it was those lines I hung the doors from.
