Only picking up on the aspect of "landmarks" when flying a circuit.
Not heard the point that when away from base those "landmarks" are gone. All that's left is the age old runway threshold at 45 degs rule (Not the start of the runway always, due to displaced thresholds) Landmarks for circuits at night may well work due to street lighting and other lights at your home airfield etc, but again, anyone relying on landmarks for circuits when landing away, is not doing it right IMHO.
