Back OT......
In the eighties, I did my school holidays as a spark's mate, putting up the lights at Walsall Arboretum
Climbing trees, dragging light (festoons?) up into them, etc etc.
One day, needing to work up one bloody huge tree, we lashed a ladder across the steps that led to the path. To stop the public from wandering into the work area.
Some old boy, 80 if he was a day, saw the ladder, dropped to his belly, slithered underneath it, got to his feet, and continued on his merry way.
"Son," he said to me "Ah bin gooin' this way for sixty 'ears, an' I ay gooin' anutha way"
