The "scene of the crime" ? Stated to be "headed south on Johnson Road, just north of Illinois Route 173..." and this looks like a good "bump" just ahead, where there's a culvert under the road. Could be. I don't see any golf courses in the area.

... well, the way they were headed, they were about 4 miles from Oak Grove Golf Course if they headed west from there on Rt. 173. If this was part of a planned circuit starting out going north then east, cutting south to the scene of the accident, it would have amounted to about 10 miles or more. Dunno. They got into it somehow.
