The only thing I know about draglines is the monstrous one that we used to climb on as kids that was left in a sand pit near Irondequoit Bay. Never grew big enough nuggets to climb all the way up the arm like some kids would. It did have a dizzying array of controls in the thing if I recall. The entire machine is now buried under a condo complex.
As an aside, this is the very area where Denonville took his troops to give the Seneca Indians a bad day. It was neck-deep poison oak in there except for the narrow trails. You fall off your bike? Get ready for some serious rashes. Denonville wrote about the sun burns and poison ivy rashes and how miserable they all were.
