Residents of the neighborhood in Chino Hills said they woke up earlier this week to discovered the misspelled instruction was printed on the road at an intersection off Peyton Drive. Advertisement "That's an F minus," 11-year-old spelling expert Matthew told CBS Los Angeles of the grade earned by the road crew. Neighbors pointed out the road crew could have referred to the nearby red and white sign if they were having trouble with the four-letter word. City officials indicated a road crew will correct the error before the end of the week.
