I walk down a little stretch of highway sometimes for relaxation on my lunch break. It's in the countryside, hilly and beautiful, with one lone farmhouse and lots of wildlife. A sign along the clean stretch of highway says,
"Adopt a Highway Litter Control by The Acker Family."
I walked along there for a month or so before I noticed the name on the mailbox: the Acker's.
So. They had a sign put up to make people notice that they pick up the trash in front of their house.
So awesome. I clean all the time, but have I ever received credit publicly? Never. And why not? Because I never put up a sign to recognize myself! Your tax dollars at work, baby!
