The crops here are different from those further west, including fields of cotton and fields of hot peppers, used in famous hot pepper sauces such as Tabasco. In the Lake Charles area, a Kansas City Southern line approaches from the north-northwest, and once had a connector that crossed on the flat at the west end of town as well as today's line that turns east paralleling the Sunset Route on the north side.
