Attention, city dwellers! We're interested in identifying university-owned or commercially managed underground urban tunnels & facilities able to host research & experimentation. go.usa.gov... It's short notice... We're asking for responses by Aug. 30 at 5:00 PM ET. The ideal space would be a human-made underground environment spanning several city blocks w/ complex layout & multiple stories, including atriums, tunnels & stairwells.
Spaces that are currently closed off from pedestrians or can be temporarily used for testing are of interest.

Tunnels, stairwells, and atriums gave it away.
Underground facilities with those features would provide “real-world” test data, while maintaining the security of being “low visibility”.
