Know the bogged feeling all too well, working on the Ghan line south of Kulgera. rained for two days then had to drive to a homestead to pick up supplies
in a FJ 45 ute older than a cockies egg, as you said bogged down to the chassis rails, took two of us 8 hours digging in the heat and flies, only to have the other guy drive it free with me yelling keep going, keep going, He stopped got out and did that toyota jump with me yelling you idiot,, look.
As he was celerbrating the ute was sinking and sinking fast, not as badly bogged but took another 4 hours to get the ute free.
I then took over the driving and the original task of going to the Homestead was completed. Had a big laugh back at camp
