In DKR Memorial there were 78 before remodel. I had the ‘opportunity’ to run them owing to minor infractions. When it was remodeled, shrunk to 75 rows. Pretty sure 56 is near the edge of upper deck overhang. At least the first to be shaded if not underneath.
Section 6 was reduced to 66 rows. Row 56 would be under the overhang. You are best served to ride the escalator up to level 7 and walk down from the restrooms and concession stand.
