St Louis is significant bc of its position on the Mississippi River means it had access to other urban areas all the way up to the Great Lakes, hence, all of North America.
The file of Pre-Reset buildings from StL show a city already built with massive beatuiful stone structures and the few people that are there only have access to a donkey and wagon. Its not a ghost city but there aren’t nearly enough ppl to build everything here.
The old energy tech has already been stripped off the buildings and the new paradigm electric grid has been installed. The canopy sheets over the doors and windows.
St Louis was home to the 1904 World Fair, the first official Olympic Games, site of the climax of the RR Strike of 1877.
