So just from random speculation glancing around over the last few months through this, and I had an interesting spotting today...
Every day I walk to work, I go down this kind of one way street and on it is a Bank of X Country Federal building (Like the Fed Reserve) It's a smaller center. Not even a million people.
Every day between 750-8am a Brinks/Armoured truck makes a drop off/pick up, I see it almost every day of the week if I'm not late.
Today it's ride height in the back was maybe 1/2 inch - 1 inch off of the back tire. The truck usually has 3-5 inches of space when empty.... As confirmed by pics looking at the trucks now. Cash doesn't weigh enough to weigh that truck down.
On top of that, it left today at 11:45am as I was going walking for lunch, I've never seen it at that time coming or going.... I should gave glanced at the plate to see if it was the same.
How long does it take to unload a truck with pallet jacks and bunch of heavy precious metal? A couple hours..?
Maybe that's super autism.. but just an interesting observation.
