I heard that back in the day, it was fisherman who left the stranded truck. I took that to mean commercial net fishermen. I suppose it broke down and they left it. But maybe someone got hurt walking out of there, and that's why they never came back.
Some old timers told me that back in the 60's they would camp out INSIDE the truck's box bed. And since it was all steel, some would make a small fire in there to keep warm.
I was told the motor is still there, just sunk in the sand. But the dirt there sort of looks like an indian shell mound, and I can't imagine a part like that NOT getting swiped.
I heard that it once said "so-n-so MILK" on the side of it since it was a milk delivery truck, hence the name Milk bus, and that makes sense because that area has been cattle country for just about forever.
I too would like to hear the true story. And I'd like to hear the lies too. It's so funny to see a truck like that in the middle of a bog.
