The Plainfield golf course, right on the border of Naperville and Bolingbrook (and thus its name), is an 18-hole facility that's actually part of the Naperville Park District. Built in 1991, it boasts all of the expected amenities, including a driving range, putting green, pro shop and concession/snack shop. Although its address might come up on your GPS as 111th Street, the road in that area is known as Hassert Boulevard.
