why go south thru Kentucky when it's supposed to go North to Canada ?
It's called 'spoke and hub' shipping. The airlines use it too.
The parcel is sent from thousands of small points destined all over the world to one large central point. The HUB
Then hundreds of parcels are packed in one container (truck or plane) and shipped to another central location, again a HUB, in the destination country.
Then the container is emptied and the parcel continues out to its final destination.
And actually, this is exactly what USPS and Canada Post (or UPS or FedEx or DHL) would do if they had been used for shipping. If I ship something from Victoria BC to Joe Batt's Arm NL,there is no direct route. It could go Victoria, Vancouver, Calgary, St Johns, JBA.
Or to NYC, perhaps Vancouver, Los Angeles, Chicago, NYC.
Sometimes knowing too much is more stressful than ignorance.
Your parcel will turn up in good time.
