I suspect a lot of that truck traffic is moving imports from the Ports of LA and Long Beach. That’s a lot of freight, but I’ll bet hardly any of it involves food products.
I believe Smithfield, makers of hams, bacon and other pork products, was purchased by the Red Chinese a few years ago.
Swine Fever is in full swing on mainland Chinese farms, and I often wonder what’s to keep spoiled meat off the markets?
Maybe it is hams and sausages coming into Long Beach via Cosco?
Also, tons of canned clams, oysters, frozen shrimp, salmon and tilapia come from China...
I could not find a single can of shellfish at Walmart that wasn’t Chinese. Didn’t buy.
