This course, one of many in the office park suburbs west of Chicago, is notable for being the location where three golfers, including the champion Lee Trevino, were struck by lightning during a public tournament in 1975. Though they all lived, lighting remains a problem for golfers, as well as spectators. The course here is also notable as it surrounds a campus of the McDonalds restaurant company, including its training center known as Hamburger University. The corporate headquarters is across the highway.
