I think the simplest explanation is that Walbridge left so suddenly Thursday to prevent the crew from catching on to how scared everyone else was and balking- Sal Paradise
Highly doubtful, highly speculative, and really doesnt mean anything
By Thursday everyone south of there was already geared up and ready for thestorm where we were. The Weather Channel and news had been forecasting for days. Unless his people were ostriches,,,didnt have any cell phones, werent internet connected at all, and lived as hermits and didnt talk to ANYONE at the docks for a week before then you could possibly be right.
They al have said they were goven the choice by Walbridge and choose to go for whatever reason. We can add your speculation to the heap of others wild speculations
