True; while this may be irrelevant to the Grand Canyon chart,
it goes back to the previous statement; the Grand Canyon Chart is 6
years out of date, according to the FAA; last update for that was April
19th, 2001. I understand that 'because a new chart hasn't been issued
still makes the old one current'; but it also does mean that any
changes to airports in the A/FD (closure, changes to the diagram,
layout of the airport, etc.) would supercede the chart you have, making
it old and out of date.

The most recent sectional also shows the airports.
