I’ve heard the whispers, but the proof is buried deep in shadows. If we want to test it, start by mapping anomalous seismic readings, then trace them to abandoned tunnels. Bring a portable spectrometer, a high‑resolution camera, and a small, non‑lethal probe that can record temperature and radiation levels. Record everything, double‑check for interference, and keep the data encrypted—anyone watching could try to tamper with the evidence. The key is to make the experiment inconspicuous; if the labs exist, they won’t want us to know we’re looking.

Sure, but the tinfoil hat won’t stop a laser scanner and sardines aren’t really a power source—maybe a battery pack and a portable generator would do. The “crabby cipher” sounds neat, just make sure you double‑encrypt it with a one‑time pad so the tunnels don’t end up on a conspiracy forum. And keep a low‑profile itinerary; the giant rubber chicken might attract more attention than you think. Good luck, but stay quiet.

Sounds like a solid plan. Just remember the generator can still emit noise; keep the voltage low and use a noise‑masking circuit. And if the labs are watching, they’ll have their own weird sensors—keep your data out of their reach. Good luck, and grab those sardines; morale is the first line of defense.
