ARCADIA, Mich. (AP) — An exclusive golf course in northern Michigan has changed its website to no longer encourage players to hit balls into Lake Michigan after a diver hired by a newspaper found hundreds in the water. State environmental regulators said they're investigating what has occurred at Arcadia Bluffs, where a round of golf on the course overlooking the northeastern shore of the lake costs $215 during the peak summer season. A beverage cart employee said she was fired for discouraging players from hitting balls into the lake.
