john roach on 12 Nov 23"There is a parallel city beneath our feet, connected by pipes and caverns, carrying rainwater, electricity, (un-)sanitary waste, and utilities. In St. Paul, It has been carved into the limestone rock for over a hundred years and extends for many miles. Above-ground pedestrians rarely notice the openings--manholes, gratings, and outfalls--and can barely imagine the subterranean spaces. That is where sound comes in: ears can judge volume,materials, shapes, and space better than eyes, in this case."
