You know how cops are always busting people with houses full of marijuana plants? What if you did all of that but with potatoes instead of marijuana? What if you had an entire house full of grow lights and potato plants in buckets and then every inch of lawn on your property had potatoes and not a single blade of grass?
Would anyone care? Would the cops come along and put a stop to it? If not, how many more potatoes would you have to grow before something like that happened?
I think (and it was a few years ago, and I could be imagining things) that the land was originally farm land. When it was sold off and subdivided into the suburb, the owner added that clause for some reason. Maybe to piss off a local brick company 🤷.
