i have a pic at work..we drilled holes 6 feet in diameter..90 feet down. peeking down to check for cleanliness, we shine light down with a mirror. it is really unsettling looking towards hell like that. we tie off with full body harnesses.
downright awesome. i have dug more post holes than i ever want to..a post hole digger is simply for taking the material out..a digging bar does the hard work. loosening the hard ground..then you grab the post hole digger for taking out the loosened materail...anyone actually digging a hole with a post hole digger is insane
or much more manly than myself..
