I don't think that's a very good example because (one could argue)
you're being radar vectored to the approach, which is specifically cited
in the AIM as one of the situations where a PT is not needed.


You're not being radar vectored to the approach in this example. The last
vector was issued by Chicago departure, Chicago Center then issued direct to
GRB VORTAC. That's the route clearance you're operating on when Green Bay
approach instructs you to join the runway 36 localizer.
