Very funny, Jim. And of course- their "consensus" is not surprising, considering that they were all employed by the same organization, and are paid to, to paraphrase the mission statement on their website, help their clients
navigate archaeological and historical compliance requirements.
They wouldn't be making much money if they told most of their clients that, no, they can't build here or there- or this or that falls under the antiquities act, would they?

I suspect that they kind of sensed that the Flagg organization wanted to unload the stones without worrying about the antiquities act... and were all too happy to oblige, all in the space of two hours.
