Okay, I suppose I deserve some shade thrown my way.
At least Derpyfingers gave me the benefit of the doubt and suggested Menards' finest cutlery, and not their discount option.
FWIW - Any digging would be out-of-sight of the authorities, in crappy crawl tunnels (not fancy caves) that the city no longer visits to access even-more craptastic crawl tunnels abandoned due to collapse. Nearly certain there are no secret entrances.
