For example, this sign was up the road from me:

I thought the story behind it was both hilarious and sad...
Apparently, the town at the next exit was planning for some future expansion of attractions in the town, they put up the sign on the highway in anticipation, but the economy went south, the town went down the tubes, and the attractions were never built.
So, for years, that blank blue sign with nothing on it except "Attractions - Exit 5" presented itself to curious drivers who wondered why the sign was there with nothing on it.
That's that sad part.
The hilarious part is some prankster saw the opportunity, created a stencil using sticky-backed reflective paper and stuck it on the sign.
I don't care who you are, that's pretty ingenious and funny!
Agreed. Good on the prankster to bring smiles to thousands of motorists faces.
Had to scale the decal correctly, drive out in the middle of the night, use a ladder....lots of work
Now that’s funny!
