What cracks me up is that the 70's bike boom bikes are held in such low regard that everyone of them will eventually be in a land fill somewhere, recycled or otherwise be disposed of. When they are all gone, perhaps one hundred years from now, someone, somewhere will have one in pristine condition and it will be worth a MINT! It will be in museum-worthy as a relic of a by-gone era.
It takes time but it will happen.
