They didn’t actually steal the trucks - just the loads. A driver pulls up to the terminal with a truck and trailer and says he is supposed to pick up a load for XYZ... brokers - the dock guys load the trailer and away you go. It happens quite frequently actually - I see it at least twice a year at one of my terminals (never successful on me). Losing a truck and trailer would be in the ballpark of a quarter mil - I run a fleet of 43 trucks for my business; you never just misplace a tractor trailer!
Leave it to California to steal Texas’ nuts. What next! :)
