The signs were drawn up by someone in one of the oil companies with specific layouts how they wanted to look. Then they put their order in to an oilfield supply house that came to us to do the work. I found 2 misspellings in some of the other signs (Most were signs listing allowed and prohibited waste materials in certain bins) I brought the misspellings to the attention of the supply house that ordered them from us and I was told to not deviate from what was supplied from the oil company. I am sure the supply house has no problem charging the oil company for fixing the misspellings when they show them it was their fault. Big ego's and big waste in the Bakken. the whole job was size, material and excess cost overkill in my opinion, but I will do them again, and again.
