Bare feet are OK in sand. Mine aren't tough enough for anything else these days though. They used to be, I didn't own any shoes until I went to school and only wore them then because you had to during school hours, but after that they often came off for the walk home.
Ok, 'nuther stuck story.
I was building Wothehellizat Mk2 in a mate's workshop, he has an earthmoving business and was out on a job mucking out a farmer's dam when the bank gave way. He managed to drop the bucket in time to support the digger and stop it from toppling over but there was no way to get it out by itself.
He drives home and we go back to the site with his motorhome.
On arrival I run the rear winch cable out to a tree to hold the truck, then we both run the front cable through a snatch block on the digger and back to the truck.
I then operate the winch from the truck cab, keeping tension on the cable so Peter can raise the boom and then walk the digger up the bank. Job done, all we have to do is take the truck back home, but now it's bogged.
By this time we'd already spooled the rear winch cable back in and were not inclined to run it back out again, fortunately the farmer had arrived by then so he pulled the truck out with his tractor.
There's no way the truck should have bogged there so we investigate and find an air line had blown so the (air operated) transfer case was not going into FWD.
All in a day's work
