They have, and all the tunnels tie in. And maybe the street names are their codes and coordinates for tunnels. Hidden in plain site, and maybe if we figure that out, we can end this sooner.

Thinking, why would they go through the trouble, the time, money and energy to build tunnels that had arbitrary endpoints?
They did go about their business in a most structured way.
So, what about Obelisks, like The Washington Monument?
2 Chron 31-1 "Now when all of this was finished, all Israel who were present went out to the cities of Judah, and smashed the [pagan] pillars (obelisks, memorial stones) in pieces, cut down the Asherim (wooden symbols of a female deity), and tore down the high places and the altars [of idolatry] throughout all Judah and Benjamin, as well as in Ephraim and Manasseh, until they had destroyed them all. Then all the sons (descendants) of Israel returned to their own cities, each to his own property."
