Several years ago, (I was white hat) during pre-game, our linesman came over and said, "we've got a problem". He proceeded to have me come over to where he was instructing the chain crew and checking the chains. The 20 yard line, although straight, was painted from the 19 yard line on the home side to the 21 yard line on the visitors side. I got both head coaches together and showed them the problem. Home coach's statement? "That's the last time I let the *&^%$ in school suspension class paint the field."
