Just another thought for you. Often the consignee’s would use the inbound freight containers loaded with their product as warehouses that often extended their allocated time for those shipping containers. Sometimes as much as a month. They then turned them to the truckers to return, and the truckers would get billed the demurrage. Of course they never would pay, and the shipper, a valued customer got off scot free. The shipping company would eat the demurrage rather than lose the shipper/consignee.
There are containers scattered everywhere - not only at LA-Long Beach but in vacant lots, RR Yards, Warehouse Parking lots, etc.
The problem is chassis - the Ports are missing 7000 chassis - there is no way to move the containers.
It is a big mess that no one has answer for.
