Buc Wheats were a maple flavoured cereal that was very popular in the '70s. However in the early '80s, they switched the flavouring from maple to honey (probably to compete with newer, trendier honey flavoured cereals in the early '80s.) And sales plummeted. It just tasted AWFUL without the maple flavour.
Unfortunately, instead of reverting back to the classic formula and saving the brand, General Mills discontinued Buc Wheats altogether in 1984.
