"Q" team's last post = 1-13-2019.
10 days darkness = 1-23-2019.
2 days ahead of schedule = 1-21-2019.
Or something like that.
The bus went around the block?
Was the bus out of view at any time?
Could the bus have dropped off a guest/product (incognito) trying to sneak away when they found out everything was cancelled?
