A big part of the problem is a CA law called AB5 that basically outlawed contract labor such as truckers. Some Non employee truckers have had to move out of CA. Lots of new rules and in a way thats arbitrary enough that no one company wants to take a chance getting anywhere near them. Some reports are its so backed up it may not catch up until next Christmas. I doubt that as new ships showing up are smaller, mostly because the big ones are so backed up from still waiting or returning from having waited. The typical backup waiting to port is usually under 2 weeks.
Anyone got details? Reading up there is so much competing info to get a reading.
