Sure, imagine a steel‑lined, low‑profile dome with motion‑sensing shutters that seal on the slightest whir. Add a mesh that can differentiate between a drone’s propeller and a rabbit’s footstep, and you’ve got a bunker that doesn’t care who’s trying to sneak in. But it’s all about the code that keeps the drones from knowing the code, and the animals from learning the scent of your tech. If you can lock that down, you’re good.

Stone wall, scent mask, tarp—cheap, quick, and if you keep the tarp low‑profile, a drone won’t notice. Just watch for any curious drone software that learns the scent code and starts pinging the wall. Keep it simple, keep it secret.
