Madison West 27 was a Low Earth footprint.
Here, in 2052, a stone pillar with a plaque affixed had been erected, on the rise that on which, in Datum Madison, the capital building had stood. It was put there by the US administration, to mark where a future community would be. Nelson Azikiwe pointed out that it was similar to Christian missionaries in England, after the Romans had left, who put crosses pagan Saxon villages they were trying to convert, as signs of future churches that would be built there.
Joshua Valienté and Nelson Azikiwe passed through this footprint during Joshua's jaunt from Reboot to Madison West 5, on his 50th birthday. When they got here it was getting dark, and Joshua could see no lights.
