I remember my grandfather came up to my house, he lived within sight of me, and saw a case of orange marking paint in my truck.
He asked about it and I gave him a couple of cans. He left really tickled
Wife came home later that day and asked me what they were going to do on the road. I asked her what she was talking about and she said it was marked up from the hill and past our place.
After going down and looking it was obvious that my grandfather had walked the road marking all perceived problems.
