Bert,
Considering your location I can see your point, as R/W and F/W traffic use much of the same airspace and route structure (with proper vertical separation of course!) in the Grand Canyon, and issues dealing with the pax (narration, "I said puke IN the bag!") are much the same for both groups too. But this is not usually the case (F/W tours of New York?) and our experiences may be of value to our fellow Rotorheads. So I'm with our esteemed moderators on this one. Let's just use the word "tour" in the thread title where appropriate and tell our plank tour colleagues about these discussions.
