I assume this course is private, but I played it on Labor Day and the many nuns we saw walking around never asked us to leave. Maybe go into the front building and ask if it is ok if you play.
Course is located along the south side of Hwy 151 (Calumet Avenue) just west (about 1.5 miles) off I-43. Turn south on Alverno Road and take your first right into the college parking area, stay right and park in the angle parking spots past the front entrance. (The first baskets you drive past are holes 5-9) First tee is located towards the northwest corner of the building.
