Uh . . . trouble is, I went back to the year BEFORE this one, 2008.
And the Schedule of Events says EXACTLY THE SAME THING THEN.
See for yourself:
The following items are PROHIBITED from entering through the gates. Individuals shall be allowed entrance ONLY after disposing or securing prohibited items.
Furthermore, screeners we will NOT hold items; the owner must dispose of or secure the item(s) in their vehicle, etc.
Weapons/knives of any type, to include ceremonial swords

This looks like a lot of nothing . . .
This information is for the people in the stands and attending the various ceremonies. Not for the NA grads.
