We can find many areas on the bumper set and the museum set that are identical. To me that's not the test for authenticity. The test is are there areas where the two sets are indisputably different. We don't need 7 points of difference as evidence. One, just one, instance destroys any argument they are the same stones. We have that. In fact; we have more than just one, but I won't belabor the point. Its no different than if you viewed a painting of the Mona Lisa with blue eyes. Would you continue to believe you were viewing De Vinci's original? Don't think you would.
The trail maps on display are duplicates, end of story (at least for me). There is lots to discuss, learn and uncover as to the why, when, who, where.
Perhaps, as I believe, the maps still reveal useful information. But, its information that may or may not be 100% accurate or revealed in its entirety. You that have the strength and ability to field check the course depicted are the true test of the maps value. When you speak, I listen. Your value to the conversation is enormous. And; in the end, when all the Peralta/Jesuit/Waltz, gold is on display it will be your field work that brought that about.
