I live in a nanny-town that has mattress tag police, and they drive three Code Enforcement vehicles around town, looking for such nuisances as car tires on porches and blades of lawn grass that are over ten inches long, the discovery of which leads to the issuance of door-hanger warnings that, if these unsightly code violations are not remedied promptly, there will be a fine to pay that can lead to a property lien. This town does not permit even one single, visible unregistered vehicle to be on the property, but it is OK to have as many unregistered vehicles on your property as you'd like as long as each is under a car cover. I see between half a dozen and a dozen such "hidden" unregistered cars every day as I drive just four to six blocks to the nearest highway, and I regard them as eyesores. Few of their covers are of optimal size, and often, the wind has dislodged at least one corner, and two people in my neighborhood either don't realize that their radio antennas can be pushed in to accommodate their covers or perhaps they have powered antennas that are broken. I do not believe that cars with old, tattered, ill fitting tarps thrown over them are more attractive than are uncovered cars without license plates. Does anyone have any idea why it is that towns require unregistered vehicles to be so cloaked?
