Night Flight Detroit - Landing

We fly with a Piper Archer III from the Ann Arbor Airport KARB to the northern part of Detroit, pass the Young Airport KDET and follow Lake Erie's coastline down to the Detroit River, where we enjoy the view on the GM tower. Next, we enter the Detroit Class Bravo airspace, where the controller allowed us to do some patternwork (!!) on runway 03R at KDTW, even though they were quite busy with the heavy metal. Finally, we return to Ann Arbor, flying right over the Detroit Metropolitan Airport's terminal building.
