Bert,
Up in Alaska many Moons ago...there was one place near Galena that was right for slinging off unworked tailings from a very productive gold mine. Plan was to stop by on the empty back haul and grab a load and drop them at a stream bed close to the work site and work it during the off season. Only thing that stopped us was the concept of Alaskan justice being much quicker than the legal system when way out in the bush.
Don't you just love the helicopter business....I am sure you know a crook or two from your travels.
