someone reported work being done with the stones just the other week or so. with machines and all. he posted pic even. what did they do? what changed? try to find out, it has to be something. and if they say that it was just some adjustments or repairing, just remember that they were built to last for thousands of years and through global catastrophy so that when all else had been lost, they would still be there to guide the people. so why would they need repair already?
